Hello! every triangle’s interior angles add up to 180. here would be how I solve this equation.
180-75-40=65 (find missing angle)
65+x=180 (supplementary angles)
180-65=x (substitution)
115=x (simplify)
x=115 (reflexive property of equality)
Answer:
Base = 6 inches
Step-by-step explanation:
30 divided by 1/2 equals 60. 60 divided by 10 equals 6.
To check:
A = 1/2bh
30 = 1/2 x 6 x 10
30 = 30 ✅
Answer:
answer C
Step-by-step explanation:
so the correct answer is the C
hope this helps
Let's solve for x.
−b3+3b2+8−(x−5b2−9)=5b3+8b2+17
Step 1: Add b^3 to both sides.
−b3+8b2−x+17+b3=5b3+8b2+17+b3
8b2−x+17=6b3+8b2+17
Step 2: Add -8b^2 to both sides.
8b2−x+17+−8b2=6b3+8b2+17+−8b2
−x+17=6b3+17
Step 3: Add -17 to both sides.
−x+17+−17=6b3+17+−17
−x=6b3
Step 4: Divide both sides by -1.
−x
−1
=
6b3
−1
x=−6b3
Answer:
x=−6b3
