Answer:
XY=4
CE=14
Step-by-step explanation:
A)since the 2 traingles are similar, there is a ratio between the 2 of them. we can find that by dividing the side :10/25 =0.4. so XYZ is 0.4 of PQR. to check that we can try to multiply pr by 0.4 to see if it gets XZ. 25 • 0.4 =10.To get XY we will do the same thing: PQ • 0.4 = 10 • 0.4 = 4
B)AB= 7
CD= AB =7
AD = 3 AB
AD = 3•7
AD= 21
Since ABCD is congruent to DEFG
AD =ED = 21
CE = ED-CD = 21-7=14

Answer:
110.1°
Step-by-step explanation:
Use the inverse cosine function (arccos or cos⁻¹).
... cos(θ) = -0.344
... θ = arccos(-0.344) = 110.1°
_____
The range of the arcos( ) function is 0 – 180°, so no adjustment of the angle is necessary. (Make sure your calculator is in <em>degrees</em> mode.)
