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:
a. √64=8
b. ∛1000=10
Step-by-step explanation:
64=8^2 Therefore, √64=8
1000=10^3 As a result, ∛1000=10
64=4^3 but each number can only be used once, so this is not possible answer.
Answer:

<h2>♪Answer :</h2>
»(4x - 2y)(3x + 5y)
»4x(3x + 5y) + (-2y)(3x + 5y)
»12x² + 15xy - 6xy - 10y²
»12x² + 9xy - 10y²
so, ABC is :
