In triangle EFG,
EG = 4.8 units
Since angle FDE = angle FED,
EF = FD = 3.5 units [sides opposite to equal angles]
FG = DE = 3 units [Given]
s = (a+b+c)/2
= (EG+EF+GF)/2
= (4.8+3.5+3)/2
= 11.3/2
now using Heron's formula,
area of EFG =
Answer:
The previous number of students are 350.
Step-by-step explanation:
Let the number of students be 100x.
x = 455
Simplify.
x = 455
Find x.
x = × 455
Simplify.
x = 350
Answer:
A) 42.7 units
Step-by-step explanation:
Here we have to use formula to find the circumference of a circle.
Circumference of a circle = 2*π*r
The value of π = 3.14
Given: The radius of the circle = 6.8
Now plug in the given value and value of π in the formula.
The circumference of the circle = 2*3.14*6.8
C = 6.28*6.8
C = 42.7
Answer: A) 42.7 units
Thank you.
subtract 2x from both sides
Subtract 7 from both sides
x is -7
I think it's D) triangle exterior angle theorem
