1a. The equation is x-35+x+5+x
Answer:
108
Step-by-step explanation:
we first add 7+8=15 then 15×2=30 30+6=36 36×2=108
Mathematics is math, geometry, algebra, calculus
Answer:
x ≈ 33.0
Step-by-step explanation:
The third angle in the triangle is
180° - 70° - 76° = 180° - 146° = 34°
Using the Sine rule in the triangle
=
( cross- multiply )
x × sin34° = 19 × sin76° ( divide both sides by sin34° )
x =
≈ 33.0 ( to the nearest tenth )
