Question

Give simple working out please

Answer 1

x = 29°

Explanation:

The sum of the measures of the angles of a triangle is 180°.

The right angle has a measure of 90°.

Angle a has a measure of 61°.

The only unknown measure of for angle x.

m<1 + m<2 + m<3 = 180°

90° + 61° + x = 180°

x + 151° = 180°

x = 29°

Answer 2

x = 29°

Explanation:

The sum of the interior angles of a triangle equal 180°

The corner with a square tells you the angle measurement is 90°

180-90-61 = 29
