Answer:
y=4
Step-by-step explanation:
Answer:
∠B
7(13)-1=90˚
Step-by-step explanation:
Are you saying ∠ABC or ABC as sides?
1. ∠ABC
(7x-1)+(4x+1)+(3x-2)=180˚
14x-2=180˚
14x=182
x=182/14
x=13˚
2. plug in
∠A
4(13)+1=53˚
∠B
7(13)-1=90˚
∠C
3(13)-2=37˚
Answer:
Step-by-step explanation:
182.5 + 50 = 232.5. 267.5 was spent
4(x+7)=38
4x + 28 = 38 - distribute the 4 into x and 7
4x = 10 - subtract 28 from both sides
x = 2.5 - divide both sides by 4 to get x by itself
answer - x = 2.5
