One of the angles of a triangle is 8 deg more than 5 times another angle. If the third angle is 4 deg larger than the difference
Mars2501 [29]

Answer:

16^\circ, 88^\circ, 76^\circ

Step-by-step explanation:

Given a triangle.

One of the angles is 8^\circ more than 5 times of one angle.

Third angle is 4^\circ more than the difference of two angles.

To find:

The angles.

Solution:

Let the first angle = x^\circ

As per question statement, second angle = 5x^\circ + 8^\circ

And third angle = 5x^\circ + 8^\circ - x^\circ + 4^\circ = (4x+12)^\circ

Using triangle sum property that the sum of all the internal angles of a triangle is always equal to 180^\circ.

x+5x+8+4x+12 = 180\\\Rightarrow 10x+20=180\\\Rightarrow 10x = 160\\\Rightarrow x = 16

Therefore, the first angle = x^\circ = 16^\circ

The second angle = 5x+8 = 5 \times 16 + 8 = 80+8 = 88^\circ

The third angle = 4x+12 = 4\times 16 + 12 = 76^\circ

Therefore, the angles are 16^\circ, 88^\circ, 76^\circ.

The complement of an angle is 8 times as large as the angle. find the measure of the complement
Feliz [49]
Complement angles means that the sum of the two angles equal to 90°.
Thus,
x + 8x = 90
9x = 90
x = 10°
8x = 80°
The complement is 80°
