Answer:
6 and 3
Step-by-step explanation:
x^2 - 9x + 18 = 0
(x-6)•(x-3)=0
if x-6 = 0 then x = 6
and if x-3= 0 then x = 3
2x^2 + 28x + 98 =
2(x^2 + 14x + 49) =
2(x + 7)(x + 7) <==
The measure of angle 1 and 2 should add up to 180°, because it forms a straight line. The same goes for the sum of angle 3 and 4.
Since we are given the measure of angle 2, we can find the measure of angle 1 by subtracting 143° from 180°.
180°-143° = 37°
We know that the intersecting lines form 2 sets of vertical angles, which are congruent. This means that the angles opposite from each other have the same measure. Therefore, both angle 2 & 4 have a measure of 143°, while angle 1 & 3 have a measure of 37°.
Answer:
9
Step-by-step explanation:
first add 3 and 5 =8
then add 1/2 and 1/2 =1
8+1 =9
