Answer:
140
Step-by-step explanation:
Angles 1, 2 and 3 are in a straight line,
Straight line has 180 degrees,
∠1 = ∠3 = 20
∠1 + ∠2 + ∠3 = 180
20 + ∠2 + 20 = 180
∠2 + 40 = 180
∠2 = 180 - 40
∠2 = 140
Answer:
7d +d +d=45
Step-by-step explanation:
The length shown for the green line is shown as 45 therefore the black line also has 45
to prove your answer:
7d + d + d = 45
9d = 45
you need to get the letter d on its own so you
9d ÷9 = 45 ÷ 9 (what you do on the one side,you do on the other)
d = 5
*substitute
5 + 7(5) + 5
= 5+ 35 + 5
= 40 +5
= 45
