a triangle has an area of 54 m2 and a height of 9m how long is the base of the triangle entered your answer in the box
2 answers:
Answer: base of the triangle = 12 mExplanation: Area of the triangle = 1/2 * base * height We are given that: area = 54 m^2 height = 9 m Substitute in the equation to get the base as follows: Area of the triangle = 1/2 * base * height 54 = 1/2 * base * 9 108 = 9*base base = 12 m Hope this helps :)
The first thing you should know to solve this problem is that the definition of the area of the triangle is: A =(1/2)* b * h Where, b: base h: height. Clearing the base we have: b = 2*A / h Substituting the values b = 2*(54) / (9) = 12 m Answer: The base of the triangle is 12m long

Answer:
145
Step-by-step explanation:
Adjacent interior angle = x
Sum of exterior angle and adjacent interior angle = 180
35 + x = 180
x = 180 - 35
x = 145

Given nth term of an AP = 7-4n
Put n = 1 then t1 = 7-4(1) = 7-4 = 3
Put n = 2 then t2 =7-4(2) = 7-8 = -1
Common difference = t2-t1 = -1-3 = -4
