Answer:
39.30°
Step-by-step explanation:
<u>In </u><u>∆</u><u> </u><u>KLM </u><u>:</u><u>-</u><u> </u>
- <u>cos</u> x = LK / KM
- cos x = 6.5/8.4
- cos x = 65/84
- x = cos -¹( 65/84)
- x = 39.30°
Answer: x=18, A=80 degrees
Step-by-step explanation:
By AA, we can say that
DEF. So:
1. Since the lengths of corresponding sides of similar triangles in equal ratio, we can say that
![\frac{AB}{DE}=\frac{AC}{DF}\\\frac{20}{30}=\frac{12}{x}\\\frac{2}{3}=\frac{12}{x}\\\frac{12}{18}=\frac{12}{x}\\x=18](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BDE%7D%3D%5Cfrac%7BAC%7D%7BDF%7D%5C%5C%5Cfrac%7B20%7D%7B30%7D%3D%5Cfrac%7B12%7D%7Bx%7D%5C%5C%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7B12%7D%7Bx%7D%5C%5C%5Cfrac%7B12%7D%7B18%7D%3D%5Cfrac%7B12%7D%7Bx%7D%5C%5Cx%3D18)
2. Since corresponding angles in similar triangles are equal, ![\angle A=\angle D=80^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20A%3D%5Cangle%20D%3D80%5E%7B%5Ccirc%7D)
<h2>Y = 7.25x + 75</h2><h2 /><h2>7.25 × 50 = 145</h2><h2 /><h2>145 + 75 = 220</h2><h2 /><h3>Therefore, Artie would have made $220.00.</h3>
You have to multiply them
