A rhombus diagonals form right angles. The diagonals also cut in half the angles
use cosine: cos38 =
a = 20cos38
a=15.8
Step-by-step explanation:
angle J is also 67 deg since the triangle is an isosceles triangle
angle T is 67 deg since the 2 triangles are congruent
angle G = 180 - 2x67 = 46 deg
ST is 5cm
HJ is 3.7cm
35.39, 35.38, 35.37, 35.36 are some numbers that round to 35.4 when rounded to the nearest tenth
