Question

In a right triangle ABC, Right angled at C,If B = 60° and AB =15 unit.Find remaining angle and side​

Answer 1

Answer:

Step-by-step explanation:

Given :- right angled at C

C= 90

Given angle B = 60

Since sum of angles in right angle is 180

Angle A+B+C = 180

A+ 90+60=180

A=180-150

A=30 degrees

Given AB= 15

Sin A=opp/hyp

Sin30=CB/AB

1/2=CB/15

CB=15/2

CB=7.5cm

Sin B= AC/AB

Sin60=AC/15

√3/2= AC/15

AC=15√3/2. { √3= 1.7}

AC= 7.5×1.7

AC=12.75

Answer 2

hey mate your ans is..

in right triangle ABC

angle C = 90

by angle sum property ...

angle B + angle C + angle A = 180 °

90 + 60 + angle A = 180

150 + angle A = 180

angle A = 180 -150

angle A = 30 °

angle A = 30

angle B = 60

angle C = 90

as the right angle triangle is not an isosceles triangle so AC is not equal to BC

so to find all the sides of triangle 2 sides must be given

if 2 sides are given then we can find the 3rd side by using pythagorus theorem

hope its helpful pls mark me as brainliest
