A. Similar triangles have equal angles even though they're not the same size that was similar means So then

X^2-5x=4x+36
X^2-5x-4x-36=0
X^2-9x-36=0
(X-12)(x(+3)
X=12. X=3

Angle C and angle F are equal
So 4(12)-5=43

Side lengths of triangle : 6cm, 12cm, and 7cm. Do these make a unique triangle, more than one triangle, or no triangle
joja [24]

Answer:

8 triangles

Step-by-step explanation:

I took this question to mean that we have the lengths, 2, 6, and 7 and have multiple copies of them. Using these lengths, what are all of the triangles that can be made?

2x2x2

6x6x6

7x7x7

2x6x7

6x6x7

6x7x7

2x6x6

2x7x7

2x2x6 and 2x2x7 don’t make a triangle.

So, 8 triangles can be made.

In the Itty Bitty High School, there are 85 students. There are 27 students who take French, 51 who take Geometry and 38 who tak
andrew-mc [135]

Answer:

58 students

Step-by-step explanation:

Given

Total = 85

French = 27

Geometry = 51

History = 38

None = 5

All = 2

Required

Students that take only 1 subjects

The attached image illustrates the question.

For French only (x), we have:

x + 7 -2+10-2+2=27

x + 15=27

Collect like terms

x =- 15+27

x =12

For Geometry only (y), we have:

y+10-2+15-2+2=51

y+23=51

Collect like terms

y=-23+51

y=28

For History only (z), we have:

z +15-2+7-2+2=38

z +20=38

Collect like terms

z =-20+38

z =18

Students with one subject is then calculated as:

1\ subject = x+y+z

1\ subject = 12 + 28 + 18

1\ subject = 58
