Answer:
49°
Step-by-step explanation:
7.5x-15+90=180
7.5x+75 =180
7.5x=105
x =14
so NPQ = ( 4×14 -7 ) = 49° this the answer
I'm pretty sure it's Identity I hope it helps :)
Use the distance formula

Input corresponding numbers

Solve



So, the distance between the points given is 5
X^2-4x-5=0
according viet’s theorem
the roots are 5 and -1
