The area of the shape is 26 square feet.
This is a composite shape. It is made up of a trapezoid at the top and two identical parallelograms on the sides.
Here are the formulas for the area of each.
Trapezoid:
0.5(2)(6 + 8) = 14
Parallelogram:
2(3) = 6
Now, just add up the 3 parts:
14 + 6 + 6 = 26
Answer:
Step-by-step explanation:
let x=1.8888...
10x=18.8888...
10x-x=18.8888...- 1.8888...
9x=17
x=17/9
So 1.8888... is equal to 17/9
Answer:
The answer is D(t) = 160 - 25t
Step-by-step explanation:
well khan academy said it lol
(7) m∠A = 52°
(8) m∠B = 117°
Solution:
(7) Let us first define the supplementary and complementary angles.
Supplementary angles: Two angles are said to be supplementary angles if their sum is add up to 180°
Complementary angles: Two angles are said to be complementary angles if their sum is add up to 90°
Given supplement of 142° = 180° – 142°
= 38°
Complement of ∠A = Supplement of 142°
⇒ Complement of ∠A = 38°
Measure of ∠A = 90° – 38°
= 52°
Hence m∠A = 52°.
(8) Given complement of 27° = 90° – 27°
= 63°
Supplement of ∠B = Complement of 27°
⇒ Supplement of ∠B = 63°
Measure of ∠B = 180° – 63°
= 117°
Hence m∠B = 117°.
