Answer:

The value of x is 6

Step-by-step explanation:

we know that

If two angles are supplementary, then their sum is equal to 180 degrees

In this problem

m∠C+m∠E=180°

we have

m∠C=112°

m∠E=(3x+50)°

substitute and solve for x

112°+(3x+50)°=180°

3x+162=180

3x=180-162

3x=18

x=6

The base of an isosceles triangle is 9 and its perimeter 49. The base of a similar isosceles triangle is 14. What is the missing

ratelena [41]

Answer: 76.2

Step-by-step explanation:

Perimetar of isiscales triangle is calculated using equation;

P=b+2a

b=9

P=49

lets find sides of triangle.

P-b=2a

a=(P-b)/2

a=49-9/2

a=40/2=20

If another triangle is similar that means that his base and sides are proportional to first triangle.

Base of first trianlge b₁=9

Base of similar triangle is b₂=14

use proportion to find out side of similar triangle:

b₁:b₂=9:14

a₁:a₂=9:14

a₁=20

20: a₂=9:14

a₂=14*20/9=280/9=31.1

Perimetar of second triangle is:

P₂=b₂+2a₂

P₂=14+2*31.1=14+62.2=76.2

Please please help me I need to learn this for my school tmr thank u very much if you do help me !!

Answer:

Step 1 :

Split the figure into 3 parts

part 1: triangle with base = 7 + 2 + 6 = 15in, height = 7in

part 2 : Rectangle with breadth = 3 + 6 + 2= 11in and length 8in

Part 3 :Rectangle with breadth 2in and length 9in

Step 2 :

find the area of each part

Area of part 1

$\frac{1}{2} * base * height = \frac{1}{2}*15*7 = 52.5in^{2}$

Area of part 2

$length * breadth = 11*8 =88in^{2}$

Area of part 3

$length * breadth = 2*9 =18in^2$

Total area = 52.5 + 88 + 18 = 158.5 sqaure inches

3 more than x
this means that whatever x is, 3 more than that
3 more means 3+ so
3+x is the answer
