Ok for 22 you just have to add both of them together and set them to equal 90. ( 4z+ 3z+6=90). then you solve for z by combining like terms giving you 7z+6=90 then subtract 6from both side leaving you with 7z=84. then divide to get z=12. you thin plug 12 into the angles such as 4(12) and 3(12)+6 which give you 48 and 42 degrees and to double check just add your 2 degrees together to form 90.

on problem 20, add both angles together and set to 180 (4h+5+8h-5=180) since the line is like half a circle. then combine like terms (12h=180) divide by 12 and then after dividing 180 by 12 and getting 15 you substitute 15 in for h.

A bus travels 12 miles in 20 minutes at this rate how many miles does the bus travel in 60 minutes

Dovator [93]

Answer:

If I'm answering this right, the bus should have travel 36 miles in 60 minutes.

If it takes 20 minutes to get to 12 miles then for every twenty minutes you would just add 12 miles.

Planes Q and R are parallel. Lines a and b are shown on planes Q and R, respectively. Planes Q and R are parallel. Plane Q conta

natita [175]

Answer:

They are skew lines.

Step-by-step explanation:

Which statement is true about lines a and b?

They are parallel lines.

They are perpendicular lines.

They are skew lines.

They will intersect.

As they both are in different directions they are skew lines .

Skew lines are not parallel neither they .They are also not co planar i.e they lie in different planes.

We have two plane Q and R . We have two line a and b on the different planes Q and R. Both planes are parallel but the lines a and b are in different directions. Therefore they are skew lines . They do not intersect and are also not parallel neither co planar.

Find the value of x.

marusya05 [52]

The two angles are vertically opposite when their vertexs share a common point on a set of two lines that cross.

2x + 8 = 70 Subtract 8 from both sides

2x + 8 - 8 = 70 - 8 Combine

2x = 62 Divide by 2

2x/2 = 62/2

x = 31 <<<<< Answer
