Well the angles should all equal 360. Since you know 90 and 160 then 360-90-160=110. Angle 2 is 90* so 110-90=20 so angle 4 is 20. Angle 2+ angle 4: 90+20=110 or C :)
Answer:
7. 69° 8. 118°
Step-by-step explanation:
to know
- isosceles triangles have the base angles congruent
- the sum of angles in a triangle is 180
180 -42 = 138 sum of the two base angles
138 /2 = 69 is one base angle
31*2 = 62 are the 2 base angles
180 -62 = 118° vertex angle
12x+3y=-17 solve for y and you will have the point slope form of the line.
3y=-12x-17
y=-12x/3-17/3 this is of the form y=mx+b where m=slope.
m=-4

2.
an isometry means the distance between any two points in the original space is the same as the distance between them in the second space.
rotation and translation are such isometries. they leave the original shape or curve unchanged in its inner structure but move it around.
so, the shapes in this question are visibly an isometry. the size and structure of the pre-image is the same as for the image. only its position changed.
4.
(x, y) -> (x-3, y+5) means that every point of the shape or curve is moved (translated) 3 units to the left (the x coordinate is decreased) and 5 units up (the y coordinate is increased).
6.
(x, y) -> (x+7, y-2) -> (x-3, y+2)
this means that first every point of the shape or curve is moved (translated) 7 units to the right and 2 units down, and then 3 units to the left and 2 units up.
in the end this means that every point moved 4 units to the right (no up or down changes, as the intermediate changes canceled each other out).
Baseball is a fun sport with a lot of history in the USA. Many families show their kids about baseball and that is how they start to like it. It gets passed on. But sports in general help you understand yourself. You get to be free and like what team you want, on play the way you want. There are many ways to understand yourself from sports <span />
