Answer:
angle C =160 degree
Step-by-step explanation:
since the given triangle is an isosceles triangle their base angles must be equal. So,
x - 10 =x/2
2(x - 10) =x
2x - 20 = x
2x - x = 20
x = 20
for angle B
x - 10
20 - 10
10 degree
for angle A
x/2
20/2
10
For angle c
angle A + angle B + angle C =180 degree (sum of interior angle of a triangle)
10 + 10 + angle C =180
20 + angle C =180
angle C =180 - 20
angle C =160 degree
Answer: Choice [D] - "power of a power" ✅
Step-by-step explanation:
Hii, do you need to know which law you should use to simplify
?
No problem!
The law we will use here is "power of a power".
What "power of powers" means is we raise a power to a power, which is exactly what we do here: We raise x^4 to the power of 9. To simplify our expression, we multiply the powers. (
)
So the right answer is: Choice [D] - "Power of a power"
The simplified answer is 
Voila! There's our answer, cheers!

Answer: 10
Step-by-step explanation:
Answer:
Step-by-step explanation:
i do not know
A is your answer
We can cross multiply using x/70=30%/100
Solving it we get:
100x=2100 (70 times 30)
x=21
So we get a, 21 as your answer.
I hope this helped!
