Question

please tell me the answer with explaination i need it

Answer 1

Step-by-step explanation:

x = 60 degrees

since the side opposite to the 90 degree is 5.6,

we can take it as 2x (30,60,90= 1:√3:2)

= 2x = 5.6

x = 5.6/2 = 2.8

so the angles if the triangle are 30, 60 and 90

x = 60

y = 45

the lower triangle is an isosceles triangle. If the one angle is 90 the other both will be equal and are 180-90/2 = 90/2 = 45 degrees
