Answer:
11
Step-by-step explanation:
2^3-(30/5)+9
First, you divide 30/5 because it is in parentheses and we are following this rule for order of operations:
P- parentheses
E- exponents
M- multiplication
D- division
A- addition
S- subtraction
so 30/5 = 6 and plugged in is:
2^3-(6)+9
Next, we do exponents:
2^3 = 2x2x2 = 8
plugged back in:
8-(6)+9
Now, we do the math from left to right so:
8-6=2
2+9=11
11 is your answer
Answer
c,116°
Step-by-step explanation:
i don't know how to draw a diagram?
Join ends of chord with the center making angles ∠2,∠3 and angle at the center.
angle at the center=128°
∠1=∠2+90°
∠2=∠3
∠2+∠3+128=180
∠2+∠2+128=180
2∠2=180-128=52
∠2=52/2=26
∠1=26+90=116°
sorry i can't explain properly without picure.
