Answer:
x = 60
Step-by-step explanation:
Perhaps you want the solution to this equation.
Subtract 0.18x from both sides:
8.4 = 0.14x
Divide by the coefficient of x.
8.4/0.14 = x = 60
Answer:
19
Step-by-step explanation:
Assume that the number is n.
sum of twice the number and 15 means that you will first multiply the number by 2 then add 15.
the equation us:
2n + 15 = -42
2n = -42-15
2n = -57
n = -28.5
Answer:
Hence,
The measure of ∠A is 60.065°

Step-by-step explanation:
Given:
ΔABC is a Right Angle Triangle at ∠ B = 90°
BC = Opposite side to ∠A = 13 unit
AC = Hypotenuse = 15 unit
To Find:
m∠A = ?
Solution:
In Right Angle Triangle ABC ,Sine Identity,

Substituting the values we get

Hence,
The measure of ∠A is 60.065°
