Answer:
For 11, x=18
Step-by-step explanation:
Use a ratio to solve for x since the triangles are similar
16/20=(16+12)/(20+x-3), first simplify both sides
4/5=28/(17+x), cross multiply
4(17+x)=5*28
17+x=5*7
x=35-16
x=18
Answer:
135. 147+x=180, x=33, 33+97=130, 130+50=180, 90-50=40 40+95=135 the answer is 135 because that angle equals the sum of the other two angles in the triangle or 180 minus the angle right next to it.
Anita first rode her bike 5 blocks to the east.
She then rode twice as many blocks west. 5*2=10. She rode 10 block west. Subtract 10 from 5: 5-10=-5
She finally rode 8 blocks back east. Add 8 to -5: -5+8=3.
Anita is three blocks east from home.
The measure of angle < APD = 98°. That is option D
<h3>Calculation of the missing angle</h3>
Angle APB = 62°
Angle DPC = 102°
But length AD = BC
Therefore, angle APD = BPC
Also, the angle at a point = 360°
The sum of the angles given = 102 + 62 = 164°
The remaining angle = 360 - 164 = 196°
Therefore angle APD = 196/2 = 98°
