Answer:

See below.

Step-by-step explanation:

We know that

tanA + tan B

tan (A + B) = ---------------------

1 - tanAtanB

Substituting for A + B

tan (A + B) = tan pi/4 = 1.

tanA + tan B

So ------------------ = 1

1 - tanAtanB

Therefore tanA + tan B = 1 - tanAtanB.

Find m. Please guys I really need your help :(

vredina [299]

Answer:

$m=\sqrt{2}$ inches

Step-by-step explanation:

From the diagram, it is given that the triangle is a right angle isosceles triangle (angles are 45°, 45° and 90°). This means that the two shorter sides of the triangle are equal in length and that the side $m$ can be found by using the Pythagorean theorem $a^{2}+b^{2}=c^{2}$ .

$m^{2}+m^{2}=2^{2}$ (The two shorter sides of the triangle are equivalent)

$2m^{2}=4$

$m^{2}=2$

$m=\sqrt{2}$ inches

I hope this helps :)

If m angle A is 155 degrees what is m angle c?

Lubov Fominskaja [6]

Hi again! If the measure of angle A is 155 degrees, then the measure of angle C is also 155 degrees because vertical angles are congruent. Vertical angles are the two angles created when two lines intersect that are NOT linear.
