Find the measure of the missing angles. 99° e f d
Answer:
e = 99 , d = 90 , f = 81
Step-by-step explanation:
Answer:
81º
Step-by-step explanation:
Notice that angle f and 99º form a straight line. A straight line is 180º, so angle f = 180º - 99º = 81º.
12. Find the measure of the exterior angle.
Answer:
68
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle
3x - 2 + 4x + 4 = 6x + 8 add like terms
7x - 2 = 6x + 8
7x - 6x = 8 + 2
x = 10
The measure of exterior angle
6x + 8 = 6*10 + 8
The measure of exterior angle is 68 degrees
Which equation represents the line that has a slope of 1/2 and
contains the point (0, 3)?
A y = 1/3x + 1/2
B y = 3x + 1/2
C y = 3/2x
D y = 1/2x + 3
Answer:
Solution given:
slope(m)=½
passing through point (x',y')=(0,3)
now
equation of a line is:
y-y'=m(x-x')
y-3=½(x-0)
y=½x+3
D.y=½x+3 is a required equation of a line.

Answer:
∠ LKJ = 64°
Step-by-step explanation:
Since KJ = KL then the triangle is isosceles with the 2 base angles being congruent, that is
∠ J = ∠ L = 58° , then
∠ LKJ = 180° - 58° - 58° = 180° - 116° = 64°
solve similar triangles (advanced)
Answer:
x = 9/4
Step-by-step explanation:
Locate point G on segment DE so that DG = 1 and GE = 4. CG is parallel to AD, so ΔCGE ~ ΔABC. Corresponding sides are proportional.
AB/BC = CG/GE
x/1 = 9/4
x = 9/4

Using the given triangles, you can write the proportion statement as ...
(9+x)/x = 5/1

Answer: 1.75
Step-by-step explanation:
5.25 / 3 = 1.75
1.75 x 4 = 7
7 + 5.25 = 12.25
1.75 x 7 = 12.25

Every week, Fred deposits $84 into his savings account, which is 20% of his weekly income. How much income does Fred make each week?
$480
$420
$510
$505
Answer: 420 dollars.
Step-by-step explanation:
Answer:
Total income, $420.
Step-by-step explanation:
if $84 is 20% of freds income, then freds income could be modeled by the equation
Income = 84/.2 which equals $420 ((((ganggang)))
to check this, you can take his total income (420) and multiply it by 20%, and if we get 84, we are correct, 20% of freds income($420) IS in fact $84.
420*.2 = $84 proving ourselves to be correct.
In the inequality -4n + 3 > 7, you will need to flip the inequality sign to solve for n. True False
