Triangle ABC and DEF are congruent. Find x.

Mathematics

blondinia [14]3 years ago

Because ABC and DEF are congruent.

m∠A = m∠D

m∠B = m∠E

m∠C = m∠F.

We need m∠B = m∠E.

m∠B = 65⁰

m∠E = (x-8)⁰

65 = x-8

x=65 + 8 = 73⁰

Answer: x=73⁰.

Δ ABC ≡ ΔDEF

⇒ ∠DEF = ∠ABC

.

<u>Solve x:</u>

x - 8 = 65

x = 73

.

Answer: x = 73°

Pavel [41]
There are 5280 feet in a mile
45 * 5280 = 237600
there are 3600 seconds in an hour (60 minutes time 60 seconds)
so we have 237600 feet in 3600 seconds
237600 / 3600 = 66 feet per second.

Answer:

  • clockwise
  • 90°
  • origin

Step-by-step explanation:

The answer statement tells you the transformation is a rotation. The original is in the 2nd quadrant, and the image is in the 1st quadrant, representing a clockwise rotation. AB points east, while A'B' points south, a rotation of 90° (clockwise). Each image point is the same distance from the origin as its preimage point. The origin is the center of rotation.

__

∆ABC is transformed by a <u> clockwise </u> rotation <u> 90 </u> degrees with a center at the <u> origin </u>.
