please help me with this math problem?

Question

a carpenter must cut two pieces of wood at angles so that they fit together to form the corner of a picture frame. what type of angles must he use to make sure that a corner results?

Answer 1

he needs to have perpendicular angles to ensure that the corner will be at a 90 degree angle.

Answer 2

ummm.. i'm really bad at maths but I'm guessing the carpenter must cut the wood on a 45 degree angle. To make a corner, the angle must be 90 degrees. So to make the two pieces perpendicular to each other they must be cut at 45 degrees (90 / 2 = 45)
i hope that was right!

Answer 3

The sum of the angles for a corner should equal 90 degrees. Therefore, each piece of wood should be cut at a 45 degree angle.

Answer 4

i dnt know, im in algebra, but i would guess a 45 degree angle cuz 45+45 equal 90 and 90 degrees are equal to like the corner of a picture frame

Answer 5

45 degree angle on both ends

Answer 6

A= 1/2BH and (reccommended) >>> C^2 = B^2 + A^2 (^=to the power of)
C being the number directly across the right angle. The... Hypotenuse? Yes. Hypotenuse. Hypotenuse being "C".
A and B being the other measures of the triangle sides.

Answer 7

45 degrees

Answer 8

45 degrees each.

both will add up to 90 degrees, forming a square.

Answer 9

i think he need complementary angles so that the sum of the two angles will be 90..

Answer 10

right angles

you couldn't figur that out your self?
