SOMEONE PLEASE HELP!!

Mathematics
1 answer:
sveta [45]3 years ago

Answer:

C, 60 degrees

Step-by-step explanation:

Since "8" is the largest length on the triangle, that must mean that 90 degrees is the largest angle of the triangle. Plus, we know that whenever an angle is 90 degrees, no other measure of the triangle can be < 90 degrees. Therefore the answer cannot be B. Since "8" and "7" are very close (7 and x are a "pair" just like 8 and 90 degrees were), we can guess that x must be relatively close to 90 degrees. Therefore the closest answer to 90 degrees without being greater than 90 is C, 60 degrees.

The length of the rectangle is 2x + 8 cm and the width is 2cm . The area of the rectangle is 12 cm​
Ksju [112]

Answer:

x = - 1

Step-by-step explanation:

Length ( l ) = 2x + 8 cm

Width / Breadth ( b ) = 2 cm

Area ( rectangle ) = 12 cm

Formula : -

Area ( rectangle ) = lb

12 = ( 2x + 8 ) ( 2 )

Divide 2 on both sides,

12 / 2 = ( 2x + 8 ) ( 2 ) / 2

6 = 2x + 8

2x + 8 = 6

2x = 6 - 8

2x = - 2

x = - 2 / 2

x = - 1

PLZ HALP. WILL GIVE BRAINIEST FOR CORRECT ANSWER WITH STEPS!!!!
mina [271]

Answer:

See below.

Step-by-step explanation:

1.

3x + 7 + 10x + 17 = 180  ( property of inside angles of 2 parallel lines)

13x + 24 = 180

13x = 180 - 24 = 156

c = 156/13

x = 12.

2.

As the triangle is a right triangle:

42.7 + N = 90

N = 90 - 42.7

= 47.3. degrees.
