Answer:
19
Step-by-step explanation:
the 2 angles shown are complementary meaning that they will add up to equal 90
x+71=90
subtract 71 from each side x=19
Answer:
Step-by-step explanation:
Supplementary angles add up to 180
∠1 + 50 = 180
∠1 = 180 - 50
∠1 = 130
∠3 +50 = 180 {Supplementary}
∠3 = 180 - 50
∠3 =130
⇒∠1 = ∠3 = 130
I^2 = -1
so,
-99 = -1*99 = i^2*99 = 99i^2
Answer:
X= -25
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
