Answer:
$4.68
Step-by-step explanation:
if you do 0.39 x 12 you get 4.68
Answer:
a. x=11°
b. ABC=106°, BCA=33° and BAC=41°
c. Sorry but I can't see the lines l and m
Step-by-step explanation:
a. the question stated that the sum of the measures of the angles in the triangle is 180°
so therefore equate all the values in the triangle to 180°
(9x+7)+ 3(x) + (3x+8)=180°
15x+ 15=180
15x=180-15
15x=165
Divide both sides by 15
therefore x=11
b. ABC=(9x+7)
where there is x put the x value you solved for there which is 11
therefore ABC=(9×11+7)= 106°
Do the same for BCA and BAC
Answer: 32
Step-by-step explanation:
1.) Write the initial equation: 2(9+7)
2.) Add the values in the parentheses: 2(16)
3.) Multiply the value in the parentheses by 2: 2(16) = 32
B = (R+2)
3R = 2B
3R = 2(R+2)
3R = 2R + 4
3R-2R = 4
R= 4
B = R + 2, so B = 6
