Answer:
x=-1
Step-by-step explanation:
-3x+8=11
subtract 8 from both sides
-3x=3
divide by -3 on both sides
x=-1
Answer:
y = 152
Step-by-step explanation:
The chord- chord angle x is half the sum of the arcs intercepted by the angle and its vertical angle, that is
(y + z) = 83 ( multiply both sides by 2 to clear the fraction )
y + z = 166
y + 14 = 166 ( subtract 14 from both sides )
y = 152
Step-by-step explanation:
Did you mean:
= (a - b)(a + b)
= a.a + b.a - b.a - b.b
= a² + ba - ba - b²
= a² - b²
Answer:
The answer is A.
