Tju [1.3M]

Answer:

$\boxed{\mathrm{x = 43.8 \ degrees}}$

Step-by-step explanation:

<em>Let the angle be x</em>

Tan x = $\frac{opposite}{adjacent}$

Where opposite = 48, Adjacent = 50

Tan x = $\frac{48}{50}$

Tan x = 0.96

x = $Tan ^{-1}0.96$

x = 43.8 degrees

When angles are complementary, the sum of their measures is 90 degrees.Two complementary angles have measures of 2x-10 degrees a

Mariana [72]

Complementary angles are those angles whose sum is 90 degree.

The measurement of two complementary angles are

$(2x-10), (3x-10)$

There sum have to be 90 degree. That is

$2x-10+3x-10 = 90$

Combining like terms ,

$5x - 20 = 90$

Moving 20 to right side

$5x=110$

Dividing both sides by 5

$x =22$

So the measurement of the angles are

$2*22-10 , 3*22-10 \\
34 degree, 56 degree$
