Answer:
Y = 59.0°
Step-by-step explanation:
Using the cosine rule in terms of x, y and z
cosY = 
with x = 22, y = 20 and z = 18
cosY = 
= 
= 
, thus
Y = 
( ) ≈ 59.0° ( to the nearest tenth )
Answer:
222
Step-by-step explanation:
Closely pay attention to the transversal line running from up-left to down-right.
y) you will notice that the angle to the right of z is corresponding with 50 then 50 will be vertically opposite 6y + 2 hence making them equal.
6y - 2 = 50
6y = 50 - 2
6y = 48
y = 6
z) vertically opposite angles are equal hence the 50 will be equal to the empty space in the triangle.
z + 60 + 50 = 180
z + 110 = 180
z = 180 - 110
z = 70
2y + 3z
2(6) + 3(70)
12 + 210
= 222
Answer:
-1
Step-by-step explanation:
=> -5 + √25 - 4(2)(3) / 4
=> -5 + 1 / 4
=> -4 / 4
=> -1
