Answer:

(A) Square root of 65

We can use Pythagorean Theorem for this, as a^2 + b^2 = c^2, that means:

4^2 + 7^2 = x^2, so 16 + 49 = x^2, add 16 and 49 and you get 65.  Remember though, x was squared, so we have to find the square root of 65. Making it the square root of 65 or (A) the answer.

46

89

180 - (50 + 41)

180 - 91

89

.ie x= 89

because total sides of triangle = 180 degree

hope this answer helps

I think the value of r is 2✓10

If r means x then it is 58.

180-61-61=58

X equals 58

180-61-61 = 58

X=40 with the little house thingy

Lemme see the triangle
