Answer:
An equilateral triangle has all three sides equal, and all three interior angles equal, too. In this case, each interior angle of an equilateral triangle is 60 degrees.
Step-by-step explanation:
Answer:
Part 1) 
Part 2) 
Part 3) 
Part 4) 
Step-by-step explanation:
step 1
Find the length side c
Applying the Pythagoras Theorem

substitute the given values



step 2
Fin the measure of angle B
we know that
In the right triangle

substitute the given values


step 3
Find the measure of angle A
we know that
The measure of interior angles in a triangle must be equal to 180 degrees
so
∠A+∠B+∠C=180°
Remember that in a right triangle the measure of angle C is 90 degrees
we have


substitute


Answer:
14.4 miles
Step-by-step explanation:
5 goes into 18 3.6 times and 3.6 x 4 = 14.4, she can run 3.6 miles per hour
Answer:
The answer will be: C: 2<em>t </em>+ 10
Step-by-step explanation:
You can check the answer by replacing <em>t </em>with any number.
Example:
I want to find the perimeter for 3 triangles. Here's how I would write the equation.
2(3) + 10 = 6 + 10 = 16
We can check by adding all the sides for three triangles.
2 + 2 + 2 + 5 + 5 = 16
Hope this helped :)
