Answer:
40 ft
Step-by-step explanation:
The fiagram shows the right triangle (one angle is right angle).
By the Pythagorean theorem,

From the diagram,

then

Prop Q because the line opposite is the biggest making it the widest angle
Let p = pictures only
let f = pictures with frames
p + f = 100
5p + 10f = 875
Solve for one variable in the first equation then plug into the second
p = 100 - f
5(100 - f) + 10f = 875
500 - 5f + 10f = 875
500 + 5f = 875
5f = 375
f = 75
75 pictures with frames were sold
Answer:
D. CPCTC
Step-by-step explanation:
THere is a statement column proof given for angle bisector construction.
Statement Justification
Angle MBP is congruent to CPCTC
angle NBP
Since the previous line proved congruence for the two triangles by SSS,
the next step is corresponding angles are equal, by corresponding parts of congruent triangles are congruent
So we have the missing justification as CPCTC
D, CPCTC
