Remember in a right angles triangle, the right angle is 90 dgrees. The sum of the three angles in a triangle is 180 degrees. Hence x + 57 + 90 = 180 x + 147 = 180 Subtract 147 from boths sides x = 33 degrees.
If it is a right triangle, you can use the Pythagorean theorem to find the height since it will be on of the sides. If it is an equilateral triangle, you can break it up into two right triangles and use the part above. If it is an oblique triangle, you use the angles and some trigonometry to find it. Since the area is 1/2 b x h, if you are given the area, you can solve for the height.
That depends on what x is: a leg, an angle, what?
Since the angles of a triangle add up to 180°, if one of the angles is a right angle (definition of a right triangle) then the sum of the other two will be 90°. If we designate the measure of the smaller acute angle as "x" then the other angle will be "4x" and: x + 4x = 90° so 5x= 90° and x = 18°
