Answer:
Step-by-step explanation:
∠A + ∠B = 180 {supplementary angles}
8x - 25 + 7x - 5 = 180 {bring the like terms together}
8x + 7x - 25 - 5 = 180 {add the like terms}
15x - 30 = 180 {add 30 to both the side}
15x = 180 +30
15x = 210 {divide both sides by 15}
15x/15 = 210/15
x = 14
∠B = 7x - 5 = 7*14 - 5
= 98 - 5
∠B = 93°
Answer:
-29
Step-by-step explanation:
2(b-4)=3(b+7)
2b-8=3b+21
2b-3b=21+8
-b=29
b=-29

Answer: the coordinates For the purple triangle A= -4,5 B= -2,1 C=-5,2
Step-by-step explanation: To the purple triangle are A( X= -4 and Y= 5 so -4,5 for a). B(X= -2.5 and Y=1 so -2.5,1 for b ). C(X=-5 and Y= 2 so -5,2 for c).
Hope this helps
