Answer:
D. None.
Step-by-step explanation:
Say the obtuse angle is 100 degrees. Since the sum of all angles in a triangle cannot be bigger than 180, it's not possible because 195 (100+95) is greater than 180 degrees. Hope this helps.

so first take two sets of coordinates. Find the slope using the slope formula; m=(Y₂-Y₁)/(X₂-X₁). Plug in the x and y values. let's use (14,21) and (2,3). Our equation would be (3-21)/(2-14)=(-18)/(-12)=1.5. Then use point-slope form; (Y-Y₁)=m(X-X₁). Plug in the x and y values, and get (y-21)=1.5(x-14). Simplify and get y-21=1.5x-21. Add 21 on both sides, and you get your final equation y=1.5x. So equation 1 will match A. Then do those same steps for the rest of the equations.

Plane A has heavier luggage with a total weight of 2,360 pounds.
Plane B has 2,320 pounds.
Because each dot represents 8 luggage cases, you can multiply the weight times the corresponding number of luggage. for example, there are 8 cases of luggage that weigh 28 pounds. In total, those 8 equal 224 pounds.

Answer:
62.83 im pretty sure.
Step-by-step explanation:
Diameter = 12 inches so the radius is 6 inches. The pan radius is 4 inches so it must be 8 inches in diameter. This means that 4 inches of the pan cannot be covered right? because 12 - 8 = 4. However because a pizza = circle you need to use pi = 3.14. So the circle area would be 113.1 - 50.27 which is 62.83
Answer:
1. The pan has lengths of 12 and 12 (remember that a pizza pan/box is a square so all sides are the same length).
That would mean the area of the pan is;
12 x 12 = 144
Now in finding the area of the pizza, we must know the formula for finding the area of a circle, which is;
A = pi*r^2,
where pi is 3.14 or 22/7, and r is the radius which is squared
So replace those values:
A = 3.14 x 4^2
A = 3.14 x 16
A = 50.24
But now they want us to find out the area of the parts that have not been covered, so we subtract the area of the pizza from the total of the pan;
144 - 50.24
= 93.76 square inches
2. To find the area of the semicircle we must use the formula for finding the area of a circle and divide it by two since it's a semicircle.
The radius of the semicircle is 3, because the diameter is 6 and half of the diameter is the radius so half of 6 is 3.
A = pi*r^2/2
A = 3.14 x 3^2/2
A = 3.14 x 9/2
A = 28.26/2
A = 14.3
Now we must find the area of the triangle,
And the formula for area of a triangle is;
A = BH x 1/2
The base is 6, and the height is 10.
So:
A = BH x 1/2
A = (6 x 10) x 1/2
A = 60 x 1/2
A = 60/2
A = 30, now we must add the total of the two areas;
14.3 + 30 = 44.3 square feet

After finding the third angle of a right triangle if the measure of one of the angles is 25°, prove how you know the measure of third angle.
a. The sum of the measures of a right triangle is 180°. You know that a right angle measures 90°. So, 180 – 90 – 25 = 55.
b. The sum of the measures of a right triangle is 180°. You know that a right angle measures 90°. So, 180 – 90 – 25 = 65.
c. The sum of the measures of a right triangle is 360°. You know that a right angle measures 90°. So, 360 – 90 – 25 = 245.

What is the surface area of this figure?
Enter your answer in the box.
ft²
1222
Reason for this answer:
The surface area of given figure is 1222 [tex]ft^{2}[/tex]
What is Surface Area ?Surface area is the amount of space covering the outside of a three-dimensional shape.
Firstly, Take the cuboidal base.
We will find the area of the front and back face which is shape of rectangle.
The side faces of rectangles and lastly the bottom face.
Area of Front and back face= area of 2 rectangles= 2 x length x breadth
= 2 x 19 x 11
= 418 [tex]ft^{2}[/tex]
Area of side faces = area of 2 rectangles= 2 x side x side
= 2 x 11 x 9
=198 [tex]ft^{2}[/tex]
Area of bottom = Length x breadth= 19 x 9
= 171 [tex]ft^{2}[/tex]
Now, area of faces remaining on the side of the triangular prism.
There are two rectangle of measurement : length= 9 ft and breadth = 4.5 ft
Area of two remaining faces on top other than triangular base= l x b= 2 x (9 x4.5)
= 81 [tex]ft^{2}[/tex]
At last, the side faces of triangular prism whose area be,=2 x 13 x 9
= 234 [tex]ft^{2}[/tex]
Area of front and back face of triangular prism= 2 x ( [tex]\frac{1}{2}[/tex] x b x h )
= 2 x 0.5 x 10 x 12
= 120[tex]ft^{2}[/tex]
Total Surface Area of the figure is,= 418+ 198+171+234+81+120
= 1222 [tex]ft^{2}[/tex]
