Answer:

$b^{2} =\frac{c^{2}-a^{2} }{4}$

Step-by-step explanation:

I believe this is the correct answer. In order to check that my equations are correct I put in some dummy numbers.

a= 2

b=4

c= $2\sqrt{17}$

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

Bishon needs to sell at least 0.3 of his collection of sports cards to make room for new cards. Is 3/20 of his collection enough

brilliants [131]

3/20 = 0.15

0.3 > 0.15

so no
