Find x and the perimeter of the triangle. <br><br> x= <br> perimeter=

agasfer [191]

Answer:

x = 10 Perimeter: 129

Step-by-step explanation:

FINDING X:

4x+7 = 5x -3

7 = x -3

10 = x

x = 10

PERIMETER:

4x + 7 + 5x - 3 + 4x - 5

Combine the "x" values

13x + 7- 3 - 5

Combine the numbers

13x - 1

13(10) -1

130 - 1

129

Given that LON is a right angle, find the measure of x.

sveta [45]

Answer:

$x=30\°$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m∠LOM+m∠MON=m∠LON ----> by angle addition postulate

we have

m∠LOM=2x°

m∠MON=x°

m∠LON=90° ----> is a right angle

substitute the values

$2x+x=90$

solve for x

$3x=90$

$x=30\°$
