Answer:
x = 50°
Step-by-step explanation:
Step 1.
180° - 80° (because there are 180 degrees in a triangle) = 100°
Step 2.
100° ÷ 2 = 50° (because the two angles on the bottom are identical, as this is an isosceles triangle - which we know because the two sides on the left and right are both the same length, 7 units)
Step 3.
Answer: x = 50°

Answer:
2
Step-by-step explanation:
add 6 to both sides and it becomes 4c=8 divide 4 by both sides and it becomes c=2
Answer:
EF ≈ 1.98
Step-by-step explanation:
Using the sine ratio in the right triangle
sin26° = 
= 
= 
( multiply both sides by 4.5 )
4.5 × sin26° = EF
4.5 × 0.44 = EF , that is
EF ≈ 1.98 ( to 2 dec. places )
Answer:
7y
Step-by-step explanation:
7yg^0 is equal to 7y(1). Anything to the power of 0 is equal to 1. This means that the expression will be equal to 7y times 1 or 7y.
