Step-by-step explanation:
sqrt(49)
What number multiplied by itself = 49
7*7 = 49
-7*-7 = 49
Answer:
<u>x = -1</u>
Step-by-step explanation:
3(x - 6) - 8x = -2 + 5(2x + 1)
3x - 18 - 8x = -2 + 10x + 5
-5x - 18 = 10x + 3
-15x = 15
<u>x = -1</u>
Answer:
BCD is the outer angle of triangle ABC
=> BCD = ABC + BAC
<=> 150⁰ = ABC + 118⁰
=> ABC = 150⁰ - 118⁰
<=> ABC = 32⁰
Answer:
i dont know sorry
Step-by-step explanation:
Answer:
Step-by-step explanation:
complementary angles, when added, equal 90 degrees
so if 1 angle is x, then the other angle, its complement, is 90 - x.
x - 18 = 90 - x
x + x = 90 + 18
2x = 108
x = 108/2
x = 54
90 - x = 90 - 54 = 36
so one angle is 54 and its compliment is 36
