Answer: 6.4cm
Step-by-step explanation:
The area of a trapezoid is given as:
= 1/2(a + b)h
We then slot the given values into the formula. This will be:
1/2(15.8 + b) × 7.3 = 81.03.
7.3(15.8 + b)= 81.03 × 2
7.3(15.8 + b) = 162.06
115.34 + 7.3b = 162.06
7.3b = 162.06 - 115.34
7.3b = 46.72
b = 46.72/7.3
b = 6.4
Therefore, the answer is 6.4cm.
Answer: ok
Step-by-step explanation:
Answer:
where is the angle if angle is not there nobody can answer this question.
Complimentary = 90 degrees
Supplementary = 180 degrees
Compliment of 51:
90 - 51 = 39 degrees
Supplement of 39:
180 - 39 = 141 degrees
The supplement of the compliment of a 51 degree angle is 141 degrees.
