Answer:
105
Step-by-step explanation:
By solving for the other triangles, we know that the angles of a triangle add up to be 180 degrees. The angle for the triangle on the left is 25 and for the triangle on the right is 50. So we have the measurements, 25, 50 and x for our middle triangle from which we can see x=105

Answer:
1,124.12 mm
Step-by-step explanation:
<u><em>Steps to answering this question : </em></u>
First determine the radius of the circle from the area of the circle
Use the radius determined above to calculate the circumference
Area of a circle = nr²
where r = radius
n = pi = 3.14
100,608.7mm = nr²
to determine the radius, divide both sides of the equation by 3.14
32,040.98726mm = r²
Find the square root of 32,040.98726mm
√32,040.98726mm
r = 179mm
Circumference of a circle = 2nr
2 x 179 x 3.14 = 1,124.12 mm
Answer:
Step-by-step explanation:
The line will not pass through the origin.
Instead, the graph will cross the y-axis at a point known as the y-intercept.
Answer:
x=21/5, also known as 4.2
Step-by-step explanation:
5x:9 = 7:3
Solve it like a proportion and get any of these answers
5x/9 = 7/3
cross product property
3(5x) = 63
15x = 63
x = 63/15 = 21/5 in fraction form = 4.2 in decimal form
