Please explain the steps and how I can find the values!!
Xelga [282]

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
