What is the length of side s of the square shown below?

this is sine rule in trigonometry therefore:

8. S

sin45

1

Step-by-step explanation:

therefore S is 5

S = 5.6569

Step-by-step explanation:

Given; let A=45° a = s B=90 ° b=8

using the sine rule;

sinA / a = sin B / b

sin45° / s = sin90° / 8

cross multiply

s × sin 90° = 8 × sin 45°

s × sin 90° = 8 × 0. 7071

s × 1 = 5. 6569

s = 5. 6569

Therefore; the length of the square is 5. 6569

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
