Answer: Triangle 4
The red triangle (that's unlabled) is reflected over the vertical line x = 6 to produce triangle 4.
Answer:
b = 10, c = 9
Step-by-step explanation:
For the triangles to be congruent by the HL postulate, then
UW = DF ( hypotenuse are congruent ), that is
12b - 34 = 5b + 36 ( subtract 5b from both sides )
7b 0 34 = 36 ( add 34 to both sides )
7b = 70 ( divide both sides by 7 )
b = 10
and
UV = EF ( legs are congruent )
4c - 9 = 3c ( subtract 3c from both sides )
c - 9 = 0 ( add 9 to both sides )
c = 9
Answer:
in triangle PQR, <P - <Q = 20 degrees, <Q - <R = 50 degrees, find <P, <Q, <R
Q = 30, R = 80, P = 50
Step-by-step explanation:
in triangle PQR, <P - <Q = 20 degrees, <Q - <R = 50 degrees, find <P, <Q, <R
R = Q
+50, 80=30+50
P = Q
+
20, 50=30+20
Q = 30, R = 80, P = 50
