Iliana's math grade increased by 21 which is 32.31%. Fiona's math grade increased by 10 which is 14.29%. To obtain the difference between the percent increases, subtract 14.29 from 32.31. Thus, the difference in percent increases of their math grades is approximately 18%.
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°
