Answer:
Area = 110.88 m²
Step-by-step explanation:
Total area = area of the two triangles + area of the rectangle
Total Area = ½bh + L*W × ½*by
= ½*7*7.2 + 7.6 × 7.2 + ½*8.6*7.2
= 25.2 + 54.72 + 30.96
Total Area = 110.88 m²
Answer:
x+87+92+105+135=540(sum of interior angle of pentagon)
x+419=540
x=540-419
x=121
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Answer:
29-(2c+3)=2(c+3)+c=
We move all terms to the left:
29-(2c+3)-(2(c+3)+c)=0
We get rid of parentheses
-2c-(2(c+3)+c)-3+29=0
Step-by-step explanation:
Answer:
x = 12
consider this a straight line:
A B C
-------------------------------------------------
<u>solve for AB</u>:
⇒ AB = AC - BC
⇒ AB = 2x - 7 - ( x - 3 )
⇒ AB = 2x - x - 7 + 3
⇒ AB = x - 4
<u>solve for x</u>:
⇒ x - 4 = 8
⇒ x = 8 + 4
⇒ x = 12
