Second question 1/42
Answer:
A.16b^4/81
step-by-step explanation:
(2b/3)^4
= (2b)^4/3^4
= (2^4×b^4)/3^4
=16b^4/81
(as 16 and 81 cant simplify each other)
Answer:
a) is the answer because line,stroke,2nd stroke =a
Answer:
x = -7, A = 65 degrees
Step-by-step explanation:
[It is important to know that in any triangle, the sum of all three angles is equal to 180 degrees]
Therefore,
x + 72 + x + 51 + 71 = 180
2x + 194 = 180 [collect like terms]
2x = -14 [subtract 194 from both sides]
x = -7 [divide both sides by 2]
To find A, we substitute the value of x into x + 72:
A = (-7) + 72
A = 65 degrees.
Hope this helps! :D
