Answer:
90
Step-by-step explanation:
A right triangle is a triangle that has a right angle. A right angle is an angle that is 90 degrees.
Answer:
70 °
Step-by-step explanation:
We have that one side of the rhombus is equal to 4 cm and an angle of the rhombus is 110 degrees. We know that the adjacent sides of a rhombus are supplementary, which means that the sum of the angles must be 180 degrees.
We can assume that the other angle is x.
110 ° + x = 180 °
x = 180 ° -110 °
x = 70 °
The measure of the missing angle on the diagram will be 70 °.
Area of the rectangle ==> 9x13 =117 cm²
Area of the right triangle ==> 11x(5)/2 =55/2 cm²
Total area = 117 + 55/2 = 289/2 = 144.5 cm²
1 radian = 57.3 degrees
