<span>2x+38=180 since all triangles add up to 180 and we have 38 as a degree we have to find the value of
2x=180-38
2x=142
x=142÷2
x=71</span>
Answer:
180
Step-by-step explanation:
The tree is 25 feet log becuase the shadow of the tree is 5 times bigger than the shadow of the pole so the tree should be 5 times bigger than the vertical pole which is 5 feet long.
Answer:
346.5 seconds
Step-by-step explanation:
Use equation t = M * 45
M =7.7
7.7 * 45 = 346.5
A=1/2(b1+b2)h - area of trapezoid
to find the height we need to look at the right triangle inside the trapezoid
in the right triangle longest diagonal is a hypotenuse, so we need to us Pythagorean theorem
