Answer:
The ratio of 3:6 means the 180 degrees has been split into 3+6 = 9 parts. One angle is 3 parts, so it = 3*20 = 60 degrees. The other is 6 parts, so it = 6*20 = 120 degrees.
Step-by-step explanation:
brainliest please
The figure is symmetrical due to the side length equalities so angleEGF=x+5 as well.
Add to the angles and set it to 360,
x+(x+5)+(x+5)+(140-x)=360
or 2x+130=360 or 2x=230 or x=115.
Excuse me but his answer is incorrect. To find the proper rate of change you might have to solve it like you would for slope.
First you would find the points for x = 3 and x = 15 would be (3, 0.08) and (15, 327.68). Then using the slope formula you can find 327.60/ 12. That gives 27.3. So in that case the correct answer is C.
X=75/17 i did the math and got that answer
Answer:
63 ft^2
Step-by-step explanation:
The hole is the rectangle minus the area of the triangle.
The area of the rectangle is
A =l*w
A = 12*6
=72
The area of the triangle is
A = 1/2 b*h
= 1/2 (3*6)
= 9
A rectangle - A triangle = A hole
72 - 9
63
