hello
so to find x, we need to use a rule.
the rule is: the exterior angle of a triangle is equal to the sum of the opposite interior angles.
so our exterior angle is xº, and the opposite interior angles are 53º and 45º.
we could set up a basic equation (although not completely necessary)
xº=53º+45º
xº=98º
hope this helps
have a nice day :)
Answer:
First one: x = 3, and y = 2
Second: 5
Third: Yes because he will have $37.50
Fourth: The numbers 2.5 and 3 will make it true
Step-by-step explanation:
1. 4(3) + 2(2) + 3 = 12 + 4 + 3 = 19
2. 4x + 2 = 22, 4x = 20, x = 5
3. 2.25y + 7.25z + 11.25, 2.25(2) + 7.25(3) + 11.25 = 4.5 + 21.75 + 11.25 = 37.5
He will get $37.50, which is enough.
4. The numbers 2.5 and 3 will make it true: 2(2.5) + 3 = 5 + 3 = 8, 2(3) + 3 = 6 + 3 = 9, the numbers below it won't make it true.
Answer:
x = 138
Step-by-step explanation:
Exterior angle thm:
68 + 70 = x
x = 138

(I answered for the equation f(x)=3x^2 - 6x +13
Step-by-step explanation:
Vertex : (1,10)
1. a= 3, b=-6, c=13
2. none
3. (0,13)
The smallest angle would be 16.26°, with the other angles being 90° & 73.74°
