Question

Find the value of x pls

Answer 1

X = 18°

Explanation:

As we can see it a right angled triangle

so <y =90°

Now

3x + 11° + 25° + 90° = 180°{being sum of angles of triangle}

3x + 126° = 180°

3x = 54°

X = 18°

Hope it will help you

Answer 2

x = 18

Explanation:

Y = 90

Z = 25
X = 3x + 11

Triangle = 180

180 = 90 + 25 + (3x + 11) --> combine 90 and 25
180 = 115 + (3x + 11) --> minus 115 both sides
65 = 3x + 11 --> minus 11 both sides

54 = 3x --> divide 3 on both sides

x = 18

VERIFY:

3(18) + 11 = 54 + 11 = 65
65 + 90 + 25 =
155 + 25 = 180
