Answer:
cosB = 2√6 / 7
Step-by-step explanation:
use the pythagorean theorem to find the missing side
a² + b² = c²
a² + 5² = 7²
a² + 25 = 49
a² = 24
a = √24
a = 2√6
--------------------------
cosB = adj/hyp
cosB = 2√6 / 7
Answer:2/3 or .666666
Step-by-step explanation:
The dilation is a contraction
Answer:
x = -13
Step-by-step explanation:
Step 1: Write equation
-104 = 8x
Step 2: Divide both sides by 8
x = -13
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-104 = 8(-13)
-104 = -104
Answer:
55%
Step-by-step explanation:
C²=A²+B²
C²= 7² + 24²
C²= 49 + 576
C²= 625
C=√625
C=25
