You are given 2/3 angles to solve for x;
24+56 = 90
90 + x = 180
x = 90 degrees

can also be written as 2i
where i = √-1

Rationalizing denominator,
Answer:
5 pounds.
Step-by-step explanation:
2 1/2 = 2.5

Answer:
7√2
Step-by-step explanation:
Thank to the give angle we can say that the two legs are congruent
b = 
98/2 = 49
49/7 = 7
7/7 = 1
98 = 7^2 x 2
√98 = 7√2
