Answer:
SAS
Step-by-step explanation:
The included angle is similar and they have corresponding sides.
Answer:
a ≈ 21.8
Step-by-step explanation:
We require the third angle in the triangle
Subtract the sum of the 2 angles from 180
third angle = 180° - (75 + 31.8)° = 180° - 106.8° = 73.2°
Using the Sine rule, that is
=
( cross- multiply )
a × sin75° = 22 × sin73.2° ( divide both sides by sin75° )
a =
≈ 21.8 ( to the nearest tenth )
A:). because if you subtract on x+2y=14 from x+3y=18 you get y=4 and letter A is the only answer with positive 4 in the y coordinate (x,y)
Since b is a variable ( unknown) we replace b with 8 since its given to us so the equation turns to 8-3-3 which we do 8-3=5-3=2
