In the center of a growing city is an old church and a high-rise office building separated by a plaza. Two surveyors are collaborating on the job of determining how high the tip of the church spire is above the plaza. Each surveyor has a theodolite mounted on a tripod. One surveyor is in the entrance way of the high-rise. The top of his tripod is 165cm above plaza level. The second surveyor is directly above the first, and (amazingly) the top of her tripod is exactly 100m above the top of her colleague's tripod. The first surveyor measures the angle of elevation of the tip of the spire as 50∘. The second surveyor measures the angle of depression of the tip of the spire as 30∘. (The diagram on the right is not drawn to scale. Points A and F are at plaza level. You'll have to supply all the necessary measurements on the diagram for yourself.)
Correct to 2 decimal places, how high is the tip of the spire above the plaza?

Answer:
180
Step-by-step explanation:
Aiko is selling books for $12 each. She wants to make more than $180 in book sales. The inequality 12b > 180 can be used to determine the number of books, b, she must sell in order to meet her goal. Which number line best represents the solution to the inequality?For which equation is x=5 a solution?
The third number line shows the inequality.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
Aiko is selling books for $12 each. She wants to make more than $180 in book sales.
and, the inequality 12b > 180 can be used to determine the number of books, b.
Now, solving the inequality
12b > 180
b > 180/12
b > 15
Hence, the third number line shows the inequality.

Answer:
m∠ABU = 70°
Step-by-step explanation:
By applying angle addition postulate,
m∠ABC = m∠UBC + m∠ABU
145° = 75° + m∠ABU
m∠ABU = 145° - 75°
m∠ABU = 70°
Therefore, measure of angle ABU is 70°.

Anthony is a high school basketball player. How many points would Anthony score in a game if he made 8 three point shots and 2 two point shots? How many points would Anthony score in a game if he made xx three point shots and yy two point shots?
Answer:
try 6
Step-by-step explanation:
because it says 8 three point shots and 2 two point shots so its 3 times 2 ig
Answer:
Anthony would score 28 points.
If he made x 3 point shots and y 2 point shots = x*3 + y*2
Step-by-step explanation:
With Anthony making 8, 3 point shots you take 8 and multiply it by 3. This gives you 24. The 2, 2 point shots he made gives you 2 multiplied by 2 which gives you 4.
So taking x*3 + y*2, plug 8 into the x and 2 into the y. This gives you 8*3 + 2*2 = 24

Answer: 1.2 in
Step-by-step explanation:
The pythagorean theorem states that a²+b²=c². Thus, 0.9²+b²=1.5².
1.5²=2.25
0.9^2=0.81
0.81 + b² = 2.25
1.44 = b²
b = 1.2
