Answer:
Step-by-step explanation:
Triangle BCZ is a right angle triangle. Triangle BCU is also a right angle triangle. Side BU is common to both triangles.
To determine m∠ZBC, we would apply the tangent trigonometric ratio.
Tan θ = opposite side/adjacent side. Therefore,
Tan B = 8/6 = 1.33
m∠ZBC = Tan^-1(1.33) = 53.06
m∠UBC = m∠ZBC/2 = 26.53
To determine CU, we would apply
the tangent trigonometric ratio.
Therefore,
Tan 26.53 = CU/6
CU = 6Tan26.53
CU = 6 × 0.4992
CU = 2.9952
Answer:
182
Step-by-step explanation:
Quotient is division
Q/-13 = -14
Multiply each side by -13
Q/-13 * -13 = -14* -13
Q =182
The unknown number is 182
Answer: Equation is
x+6+x+9+x+3 = x+4+x+4+x+1+x+1
Solved x=8
Work:
Answer:
4:18, 6:27, etc
Step-by-step explanation:
Basically, anything x 2 and x 9 would be equivalent as a ratio
8+5=13 because 4×2 ÷8 and 8+5=13
