Answer:B
Step-by-step explanation:
1.
The edge lengths of a triangle are inversely proportional to 2,3 and 4.
The actual proportions of the lengths are then
12(1/2:1/3:1/4)=6:4:3
The longest side
= 39* (6/(6+4+3)
= 39*6/13
=18
2. 63 breads : 35 kg flour
is the same as
54 breads : x kg flour
Cross multiply and get
x=54*35/63=30
30 kg of flour are needed to make 54 breads.
Answer:
D. 35 + 145 = x
The sum of the angles = 180 degree
Step-by-step explanation:
Step 1: Find X
3x + 7 + 9x + 17
Add the alike terms: 12x + 24
Linear is 180 degree, 12x + 24 = 180; now find x
X = 13
Now find the degree for both.
RST: 3 (13) + 7 = 46
VST: 9 (13) + 17 = 134
You're answer is A
