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

Answer:
= (3t+2)(3t-2)(3t-4)
Step-by-step explanation:
Given the expression 27t^3 - 36t^2 - 12t + 16
On factoring:
(27t^3 - 36t^2) - (12t + 16)
= 9t²(3t-4)-4(3t-4)
= (9t²-4)(3t-4)
factoring 9t²-4
9t²-4 = (3t)² - 2²
From different of two square, a²-b² = (a+b)(a-b)
Hence (3t)² - 2² = (3t+2)(3t-2)
= (9t²-4)(3t-4)
= (3t+2)(3t-2)(3t-4)
Hence the factored form of the expression is  (3t+2)(3t-2)(3t-4)
