Answer:
Lets say its a right angle : we know that it is 90 degrees
Since triangles are congruent to each triangle, each triangle has half as many degrees, namely 180. So this is true for any right triangle.
Answer:
1) x=67, y=83, z=80 2) x=5
Step-by-step explanation:
1) 28+85=113 a triangle is 180 degrees so 180-113=67 so x=67
x and y are supplementary meaning both sides equal 150 so 150-67=83
83+17=100 now going back how much did i say a triangle should equal? 180 so z is 80
2)a triangle = 180 since the triangle is a right angle it includes the angle 90 so make the equation to solve for x
180=90+8x+2+9x+3
take 90 to other side so you are subtracting 180-90
90=8x+2+9x+3
combine like terms
90=17x+5
subtrcat 5 from 90
85=17x
now divide 85 by 17 and you get x=5
Answer: 3 yards
Step-by-step explanation:
1 yard = 3 feet so 3 yards =9 feet
Let's say u put those 2 patterns onto a graph it would be (x,y) (3,5). same for the next (6,10). I'm sorry if this didn't help I'm trying though
