Answer:
1) 25 miles
2) 20 m
Step-by-step explanation:
Number 1 is going to be
because it's a right triangle
So
+ 
= 
625 =
c = 25 mile
Number 2 uses the same process, but changing to using C instead of A
a^2 = c^2 - b^2
a^2 = 625 - 225
a = \sqrt(400)
a = 20m
Answer:
a < 16
Step-by-step explanation:
We must get a alone to solve this. So first multiply by 2
3a/2 < 24
*2
3a < 48
Divide by 3
a < 16
Answer:
7. x=3, 8. x=7, 9. x=15.
Step-by-step explanation:
7. If lines m and n are congruent, then angles DCF and CFE are congruent. 15x+3=18x-6. Solve for x. --> 15x+9=18x-->3x=9-->x=3
8.If line m is parallel to line n, then the corresponding angles are congruent. So, 20x+1=22x-13 Solve for x. 20x+14=22x-->14=2x-->x=7.
9. The supplementary angle of 110 is 70. Note that all of the inner angles of a triangle are equal to 180. Form an equation using the the values: (4x+8)+(2x+12)+70=180. Simplify; 6x+90=180. Solve for x: 6x+90=180-->6x=90-->x=15.
Hope this helps!
To find percent, you take 91 and divide it by 99.2 then multiply by 100.
(91/99.2) × 100 = 91.92%
