The answer is 15. 37 plus 18 equals to 55 and 22 plus 18 equals to 40. 55 minus 40 equals to 15.
Hey there! :)
Answer:
x = 65°
Step-by-step explanation:
Find the measure of the other two angles using the Supplementary Angles theorem:
180 - 105 = 75°
180 - 140 = 40°
The sum of all of the angles in a triangle is equal to 180°, therefore:
180 = 75 + 40 + x
180 = 115 + x
65 = x
x = 65°
Perimeter:24 units
Horizontal side is 7 units and vertical side is 5 units. You first multiply 7 by 2 and 5 by 2. You will get 14 and 10. Then, you add 14+10. The answer would be 24.
9 mph because if it was 4/5 miles in 1/10 of an hour you just multiply it by 10 to get an hour and if you multiply 4/5 x 10 equals 40/5. simplified it is 9
