Question

- Draw and estimate the angle in standard position whose sine ratio is 0.57​

Answer 1

Given : sine ratio is 0.57​

To Find : estimate the angle in standard position

Solution:

Step 1 :  Draw a ray  AX

Step 2 : draw a right angle at A using protractor

Step 3 : Take  a length of 5.7 cm from A on angle drawn and mark as B

Step 4 : Using compass width = 10 cm and taking B as center  draw an arc intersecting at AX C,

Sin C = 5.7/10  = 0.57

Measure Angle C using protractor

∠C ≈ 35°
