lot of questions here lets try the first one m<2=x+8 and m<3=2x+7

OpenStudy (anonymous):

i dont want answers just help

12 years ago

OpenStudy (anonymous):

angle 2 and angle 3 together add up to 90 degrees because the internal angles of a triangle add up to 180 degrees

12 years ago

OpenStudy (anonymous):

so \(x+8+2x+7=90\) and you can solve for \(x\)

12 years ago

OpenStudy (anonymous):

\(3x+15=90\) \[3x=75\]\[x=25\]

12 years ago

OpenStudy (anonymous):

so m2= 25+8=33

12 years ago

OpenStudy (anonymous):

and m3 = 2*25+ 7 = 57

12 years ago

OpenStudy (anonymous):

57 or 33

dont need help for #1

OpenStudy (anonymous):

thats the one from lsat time 33

Directrix (directrix):

#2 If two angles of a triangle are congruent, then the sides opposite those angles are congruent. So, what type triangle is it?

12 years ago

OpenStudy (anonymous):

equiangular triangle

12 years ago

OpenStudy (anonymous):

no im wrong

12 years ago

Directrix (directrix):

No, equiangular would be all three angles congruent. We know exactly TWO angles are congruent.

OpenStudy (anonymous):

iisosceles triangle

12 years ago

Directrix (directrix):

Yes, isosceles.

OpenStudy (anonymous):

I got #3. Is it alternate interior angles are always congruent

12 years ago

Directrix (directrix):

Yes, that is correct. Good!

Directrix (directrix):

#4 y = (-1)x + 2 and y = (1) x + 10 are equations of perpendicular lines. What is the product of their slopes?

12 years ago

OpenStudy (anonymous):

The product of the slopes is 1.

12 years ago

Directrix (directrix):

Negative one times positive one is NOT positive one. Try again!

12 years ago

OpenStudy (anonymous):

-1

12 years ago

Directrix (directrix):

Yes, the product of the slopes of perpendicular lines is -1 under the stipulations of the given problem.

12 years ago

Directrix (directrix):

The measure of an exterior angle is equal to the sum of the measures of the two remote interior angles. m<ACD = 60 + 80 m<ACD = ?

12 years ago

OpenStudy (anonymous):

140

Directrix (directrix):

That is what I got for #5.
