A. 27. 
we can prove that the two triangles within the triangle are congruent (the triangle is an isosceles) with SAS. then we do 180- (63 x 2). then we get the top angle. and then we divide 54 by 2 to make the individual angles and then we get 27.

Write the equation of the line passing through the point ​(​6,-9​) with slope -5/6.
Brilliant_brown [7]

Answer:

The equation is y = -5/6 x-4

Step-by-step explanation:

The equation of a line in slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = -5/6 x+b

Substitute in the point

-9 = -5/6(6) +b

-9 = -5+b

Add  5 to each side

-4 = b

The equation is y = -5/6 x-4

Tell weather the two rates form a proportion. help
Sindrei [870]
7/9 = 42/54...when 42/54 reduces, it becomes 7/9...so this is proportional because proportions are nothing but equivalent fractions.

u could also check it this way...
12/21 = 15/24
cross multiply
(21)(15) = (12)(24)
315 = 288.....these do not equal and are therefore, not proportionate

440/4 = 300/3
110 = 100....not equal, so not proportionate

120/5 = 88/4
24 = 22.....not proportionate

66/82 = 99/123
0.804 = 0.804.......these are proportional

68/172 = 43/123
0.395 = 0.349......nope, not proportional

BRAINLY!!!- if a=7, b=8, and c=9.2 is this a right triangle? why?
Travka [436]

Answer:

no

Step-by-step explanation:

If this were a right triangle we would assume the Pythagorean Theorem to prove it

a^{2} +b^{2} =c^{2}

7^{2} +8^{2} =9.2^{2}

this gives us

49+64=84.64

this is 143=84.64 and therefore not equal and not a right triangle
