The angles of a triangle add up to 180 degrees
65 + 3x - 10 + 2x = 180
5x + 55 = 180
5x = 180 - 55
5x = 125
x = 125/5
x = 25 <====
m < B = 3x - 10 = 3(25) - 10 = 75 - 10 = 65 <== B is 65 degrees
m < C = 2x......= 2(25) = 50 <== C is 50
Answer:
the value of x is 13 because 2 times 13 equals 26 and 26 plus 6 equals 32.
The number 20 has TWO square roots which are -20 and 20.....I hope this helps!!! Have a great day!!
