Question

Please help me this is geometry

Answer 1

a = 70.71068 = 50√2

Explanation:

• Given c=100 and ∠β=45°,
• a = 70.71068 = 50√2

a = √c^2 - b^2

= √1002 - 70.7106781186552

= √5000

= 70.71068 = 50√2

Thanks.

Answer 2

50

Explanation:

Since 45-45-90 tri, x^2+x^2=100^2

So 2x^2=10000

2x=100 and x=50
