Answer:

1)  (c)∠ G = 34°

2) (a)  x = 33°

3) (d) The perpendicular segments are  JM, KL, PQ AND NR.

Step-by-step explanation:

Here in the given questions:

1)  p II r

⇒ ∠ G  = 34°  (ALTERNATE EXTERIOR ANGLES)

Hence, the measure of  ∠ G = 34°

2) In the given triangle:

The measure of exterior angle is always the sum of interior opposite angles.

⇒ Here, x + 72°  = 105°

or, x = 105° - 72° =   33°   , or x = 33°

3) The given plane in the cube is JKPN

The segments which have J , K , P and N as their one vertex are perpendicular to the given plane.

Hence, the segments are  JM, KL, PQ AND NR.

Simplify h= 105sin (0.0698(90+1)) + 105
IrinaK [193]

Answer:

h= 116.616

Step-by-step explanation:

we have

h= 105sin (0.0698(90+1)) + 105

step 1

Solve (90+1)

h= 105sin (0.0698(91)) + 105

step 2

Solve 0.0698(91)

h= 105sin (6.3518) + 105

step 3

Solve sin (6.3518)

h= 105(0.11063) + 105

step 4

Solve 105(0.11063)

h= 11.616 + 105

step 5

Solve 11.616 + 105

h= 116.616
