Answer:
x = 34.915°
Step-by-step explanation:
law of cosines
angle = arccos (b^2+c^2-a^2/2bc)
angle
Answer:
z≤2
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
−1/8z≥−0.25
Step 2: Multiply both sides by 8/(-1).
(8/−1)*(−18z)≥(8−1)*(−0.25)
z≤2
Step-by-step explanation:
7x + 8 + 15 - 7x
Solving like terms
23
Option C is the correct answer
First do distributive property
2x + 10 + 3x = 30
Now combine like terms
5x + 10 = 30
Subtract 10 from both sides
5x = 20
Divide both sides by 5
x = 4
