H= 79
add 7 to both sides.
Answer:
Measure of angle A is 65 degrees and measure of angle B is 37 degrees.
Step-by-step explanation: First add all of the degrees of excluding x (4+(-9)) which is -5. Then subtract that from 180 since that is the sum of all the angles in a triangle which gives you 185. Then divide it by the number of "x's" that there are which is 5 which gives you 37. So angle B is x which is 37 degrees and angle a is 2(37)-9 which is 65 degrees. Hope this helps.
Step-by-step explanation:
3 (x - 2) =12
(x-2) = 12/3
(x-2) = 4
X= 4/-2
X= - 2
Answer:
d. BC=30
Step-by-step explanation:
triangle ABC is cut by a diagnal AD into two equal triangles .So if BD is 15 ,DC will also be 15
therefor total length of BC wil be 30 (15 +15)
Answer:
$29.93
Step-by-step explanation:
First, we take the discount off of the original price.
We need to find the discount amount in dollars.
30/100=.3 this is 1%.
.3 * 5 = 1.5 He will get $1.50 off of his purchase.
30 - 1.5 = 28.5.
Next we will add tax. We need to find tax in dollars.
28.5/100=.285 this is 1%
.285 * 5 = 1.43 He will get $1.43 of tax on his purchase.
28.5 + 1.43 = 29.93
He will pay $29.93 for his wind chime.
