7:120 i think thats what its asking
Answer:
X =6
Step-by-step explanation:
Angles on a straight line add up to 180°
180-110=70
The 70° is the same on the angles above
70+8+17x=180
180-70=110
110-8=102
102/17=6
X=6
Answer/Step-by-step explanation:
1. Side CD and side DG meet at endpoint D to form <4. Therefore, the sides of <4 are:
Side CD and side DG.
2. Vertex of <2 is the endpoint at which two sides meet to form <2.
Vertex of <2 is D.
3. Another name for <3 is <EDG
4. <5 is less than 90°. Therefore, <5 can be classified as an acute angle.
5. <CDE is less than 180° but greater than 90°. Therefore, <CDE is classified as an obtuse angle.
6. m<5 = 42°
m<1 = 117°
m<CDF = ?
m<5 + m<1 = m<CDF (angle addition postulate)
42° + 117° = m<CDF (Substitution)
159° = m<CDF
m<CDF = 159°
7. m<3 = 73°
m<FDE = ?
m<FDG = right angle = 90°
m<3 + m<FDE = m<FDG (Angle addition postulate)
73° + m<FDE = 90° (Substitution)
73° + m<FDE - 73° = 90° - 73°
m<FDE = 17°
Answer:
A. P=11*3 = 33 ft
A= 21*3 = 63 ft^3
B. P = 9*3 = 27 ft
A = 15*3 = 45 ft^3
C. P = 20*3 = 60 ft
A = 24*3 = 72 ft^3
D. P = 13*3 = 39 ft
A = 25*3 = 75 ft^3
