uh what's the question- there needs to be a question to be an answer >.< i'll edit this answer once you tell me the question
Step-by-step explanation:
Answer:
not enough information
Step-by-step explanation:
Perpendicular lines intersect at right angles. Since lines c and b are perpendicular, angles 1, 2, 3, and 4 are right angles, and each one measures 90 degrees.
Angle 2 is formed by the intersection of lines a and b. We are not told anything about the intersection of lines a and b, and we are not told anything about the relationship between lines a and c, so we do not have enough information to determine the measure of angle 2.
Total cost for tiles and paints is $924.
Step-by-step explanation:
We have been given that a community hall is in the shape of a cuboid. The hall is 40m long 15m high and 3m wide.
The paint will be required for 4 walls and ceiling.
Let us find area of walls and ceiling.
Therefore, the area of walls and ceiling is 1410 square meters.
Given: Cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. Therefore,
Therefore, the total painting cost is $564.
Tiles will be required for floor. Let us find the area of floor.
Given: 1m squared floor tiles costs $3. So,
Therefore, the total cost for tiles is $360.
Now let us find combined total cost of tiles and paint.
Therefore, the combined total cost of tiles and paint is $924.

(87+91+86+x)/4=90.
x=96.

50×y > 130.
the lowest number could be 3, because 50×2=120, which is less than 130.
Answer:
<MBK because of the isosceles triangle theorem. If two sides of a triangle are congruent, it is isosceles, so the angles opposite them are also congruent.
