Answer:
18° and 72°
Step-by-step explanation:
The angle measures are unknown, so they will be represented with the variable, x. Since, one angle is 4 times the other, this will be represented with 4x.
To find complementary angles, they are added together and equal 90. So let's create an equation.
x + 4x = 90
Now solve for x.
5x = 90
5x/5 = 90/5
x = 18
One angle is 18°.
Now find the second angle.
4x
plugin 18 for x and multiply
4(18) = 72
Answer:
A. 322 mm^2
Step-by-step explanation:
The area of the rectangle is 14 times 20
14 x 20 = 280
The area of the rectangle is 1/2 times 14 times 6
1/2(14)(6)=42
Finally add 280 and 42 and the answer is 322
Answer:
Plane A will be farther because it is flying at a lower angle so it will be able to cover more ground by flying slightly more forwards than going more upwards like plane B
The answer is 0.40 or 0.4
