Question

Please explain the steps and how I can find the values!!

Answer 1

Answer:

a = 4.949

b = 4.949

c = 7

Step-by-step explanation:

c ( hypothenuse ) = 7

to find a, use sine

Sine = $\frac{opposite}{hypothenuse\\}$

Sine 45 = $\frac{a}{7}$

sine of 45 is 0.707

0.707 = $\frac{a}{7}$

multiplt 7 on both sides:

0.707 x 7 = $\frac{a}{7}$ x 7

a = 4.949

to find b, use cosine

Cosine = $\frac{adjacent}{hypothenuse}$

Cos 45 = $\frac{b}{7}$

cos of 45 is 0.707

0.707 = $\frac{b}{7}$

multiply 7 on both sides:

0.707 x 7 = $\frac{b}{7}$ x 7

b = 4.949
