In a right triangle with a leg of 4 and a hypotenuse of 8, find the measures of all angles.

90° , 60° and 30° .

Step-by-step explanation:

Given : In a right triangle with a leg of 4 units and a hypotenuse of 8 units.

One angle should be 90°. (A right triangle has a 90° angle.)

Let the given leg is the side opposite to the angle  in the triangle.

Then by trigonometry , we have

 [Sine of an angle is the ration of the side opposite to the angle and the hypotenuse of a right triangle.]

Also ,

Let  x be the measure of the third angle.

BY Angle sum property of triangle , we have

Therefore , the measures of all angles in the triangle : 90° , 60° and 30° .

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
