Answer:

See below ~

Step-by-step explanation:

Given : 3 angles of a Δ

(x + 5)°
(x + 10)°
(x + 15)°

Solving :

According to Angle Sum Property of a triangle, the angles of a triangle add up to 180°
x + 5 + x + 10 + x + 15 = 180
3x + 30 = 180
x + 10 = 60
x = 50

Finding the angles

x + 5 = 50 + 5 = 55°
x + 10 = 50 + 10 = 60°
x + 15 = 50 + 15 = 65°

Christian wants to make an A in his class. There are 5 exams this year, and he has taken 4 of them. His grades were 84, 88, 95,

ioda

Answer:

last test grade=x x ≥ 79 so 79%

Step-by-step explanation:

(84/5)+(88/5)+(95/5)+(104/5)+(x/5) ≥ 90

Simplify: (371/5)+(x/5) ≥ 90

Subtract (371/5) from both sides

Then you have (x/5) ≥ (79/5)

Then multiply both sides by 5 and you have x ≥ 79

P.S. If it was helpful please consider giving me brainliest. =)
