Answer:
100°
Step-by-step explanation:
The sum of the angles in a triangle is 180°
180°-30°-50°=100°
Isolate the variable by dividing each side by factors that don't contain the variable.
x= 13/4 - y/4
If you are solving for x (only)
X = 45/4 - y/4
If you are solving for y (only)
Y= 45- 4x
Answer:
<h2>The answer is 15cm</h2>
Step-by-step explanation:
Let b be the length of the second parallel side
Area of a trapezium is given by

where
h is the height
a and b are the parallel sides
From the question
Area = 230 cm²
height = 20cm
one of parallel side / a = 8 cm
Substitute the values into the above formula and solve for b
That's

Reduce the fraction with 2
That's

Expand the terms
That's


Divide both sides by 10
We have the final answer as
<h3>b = 15cm</h3>
