The roof will be in the shape of an isosceles triangle with a base length of 30 m and two sides that are 17 m. The two 17 m beams will have the same angle of elevation since they have to might in the middle.
So to find the angle of elevation, we can split the roof in half vertically to create a right triangle. The base will now be 15 m, and the hypotenuse will be 17. Now we can use a trigonometry function to solve for the angle. We know the hypotenuse and the side adjacent to the angle, so we can use cosine.
The answer is 28.1 degrees
Answer:
A. 14%.
B.
Step-by-step explanation:
We have been given that a running back was the MVP (most valuable player) in 0.14 of the first 50 Super Bowls.
A. To find the percent, when the MVPs were running backs, we need to convert 0.14 into percent by multiplying by 100 as:
Therefore, 14 percent of the MVPs were running backs.
B. To find the fraction of the MVPs were not running backs, we will subtract 0.14 from 1 to find the MVPs, who were not running backs. Finally, we will convert the answer into fraction as:
Now, we will multiply and divide 0.86 by 100 as:
Reduce the fraction by dividing numerator and denominator by 2:
Therefore, of the MVPs were not running backs.
Answer:
70 mm
Step-by-step explanation:
Use PYTHAGOREAN THEOREM: a^2+b^2=c^2
42^2 + 56^2 = c^2
1764 + 3136 = c^2
4900=c^2
square root of 4900 is 70
so, the final answer is 70 mm
Answer:
x = -16
Step-by-step explanation:
-1/3 * 9x = -3x
-1/3 * 30 = -10
-10 + 2 = -8
40 = -3x - 8
+8 +8
48 = -3x
--- ----
-3 -3
-16 = x
x = -16

Since we have the triangle, but don't know which side 4 is on, we have one where x is opposite a 50 degree angle (they are the same if across either 50 degree side) and another across the 80 degree one. In addition, it's really ratios and sin/cos/tan from there!
