Answer:
1) 60°, 75°, 120°, 105°
2) 101.5 m
Step-by-step explanation:
1) The sum of ratio units is 4+5+8+7 = 24, which corresponds to the sum of angles, 360°. Then each ratio unit must stand for 360°/24 = 15°. Multiplying the given ratio units by 15° gives the angle measures:
- 4×15° = 60°
- 5×15° = 75°
- 8×15° = 120°
- 7×15° = 105°

2) The similarity statement and the scale factor mean ...
MJ : TQ = 4 : 7
7·MJ = 4·TQ . . . . . . . . . "cross multiply"
TQ = 7/4×MJ = 7/4(58 m) . . . . . divide by 4, substitute the value of MJ
TQ = 101.5 m
2/5
How? The decimal .4 is out of ten so it’s 4/10 but then you simplify it and get 2/5
Hope this helps and have a blessed day!
You can only simplify it, because you can't add a number with x to a number without, so it would be 7x+7
