Answer:
Base 12m Height 5m
Step-by-step explanation:
Area of a triangle formula A=1/2bh
30=1/2(x)(x-7)
2*30 = 1/2(x)(x-7)*2
60 = x^2 -7x
60 - x^2 + 7x = 0
-60 + x^2 -7x = 0
x^2 -7x -60 =0
x^2 + 5x -12x -60 = 0
x(x+5)-12x-60=0
x(x+5)-12(x+5)=0
(x+5)*(x-12)=0
x+5=0
x-12=0
x=-5
x-12=0
x=12
The final answer is: x= 12,5
get rid of the -5 because -5 does not make sense at a height so turn it into 5
Base: 12m
Height 5m
Answer:
the answer is DBC=90°
because the midpoint of the perimeter of quadrilateral is B
The fraction of the cake that was ron's pieces is 1/5.
<h3>What is the fraction of the cake was ron's pieces?</h3>
Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).
Since Mrs Jones gave 1/5 of a cake to her neighbour, the remaining fraction will be:
= 1 - 1/5
= 4/5
The fraction of the cake that was ron's pieces will be:
= 2/(1+3+4) × 4/5
= 2/8 × 4/5
= 8/40
= 1/5
