At first, we need to find x.
QR = LN
2x+1 = 3x-7
x=8
Substitute value of a=8 into QR = 2x+1.
QR = 2*8+1 = 17
QR =17
Answer:
x=30, <A=60, <C=30
Step-by-step explanation:
A triangle always has its total angles added up to 180 degrees, so we can set up the following equation:
90+2x+x=180
90+3x=180
3x=90
x=30
Since x=30, this means <C is 30 degrees. For <A, it's twice as much as <C, so 2*30=60.
So x=30, <A=60, <C=30
