One of the unknown angles (let's called it n) has a complement (meaning their sum adds up to 90 degrees) and the other angle is 8 times the unknown angle (8n)
With all this information, you should have the equation:
n + 8n = 90
To solve, combine like terms to get:
9n = 90
Divide by 9 on both sides to isolate the variable n.
n = 10
Now we plug back in to find our angle measurements. The first angle, n, is 10 degrees. The second angle, 8n, is 8 * 10 which is 80; the second angle is 80 degrees.
Answer:
x=8
Step-by-step explanation:
Answer:
im not really sure but i think its b
Step-by-step explanation:
Answer:
2×5×8 = 80
80+1 81
There are 81 students in the camp
Step-by-step explanation:
This is a straight line equation. We only need two points to draw a straight line.
Choose two different numbers, put them into the equation instead of x, and calculate the value of y.
for x = 8
<h2>(8, 1)</h2>
for x = -8
<h2>(-8, 3)</h2>
Mark the points in the coordinate system and draw a straight line through the given points.
