Answer:
m=-8/3
Step-by-step explanation:
1/m+4=3/4
cross multiply over the equal sign
1×4=3(m+4)
4=3m+12
combine the like terms
4-12=3m
-8=3m
divide by 3
-8/3=3m/3
m=-8/3

Step-by-step explanation:
Answer:
θ = 55° (Approx)
B = 16.5 (Approx)
Step-by-step explanation:
Given:
In Δ first;
H = 7
B = 4
Cos θ = B/H
Cos θ = 4 / 7
Cos θ = 0.57
θ = 55° (Approx)
Given:
In Δ second;
B = x
P = 8
θ = 26°
Tan θ = P / B
Tan 26° = 8 / x
0.4877 = 8 / x
x = 16.5 (Approx)
B = 16.5 (Approx)
Answer:
Y = 40
Step-by-step explanation:
First find the measure of V
The sum of the angles of a triangle equal 180
U+V+W =180
70+Y+70 =180
140+U =180
U = 180-140
U = 40
Since the triangles are similar
V = Y
40 = Y
