A side of the triangle below has been extended to form an exterior angle of 155°. Find the value of xx.

Step-by-step explanation:

Find a similar diagram attached

Let the exterior angle be 155°

The sum of interior angle is equal to the sum of the exterior angle of the triangle

Interior angle are angles inside the triangles

Sum of interior angles = 90 + x

Exterior angles are those outside the triangle.

Exterior angle = 155°

Since sum of interior = exterior, hence;

90 + x = 155

x = 155 - 90

x = 65°

Hence the value of x is 65°

Note that the same concept can be used for any other triangle extending to form an exterior angle

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
