d-15.6=2d-556.3 d=540.7
9b-10=2(3b+4) b =6
Step-by-step explanation:
I think it would be the first one because it is smaller
Answer:
The ratios are equivalent.
Step-by-step explanation:
If you multiply both 5 and 6, the ratio stays the same.
5:6 = 10:12 = 15:18 = 20:24 etc.
You can try this by dividing the larger number by the smaller number. You'll always get 1.2 as the "relationship", or ratio, is preserved.
24/20 = 1.2
15/18 = 1.2
10/12 = 1.2
6/5 = 1.2
Answer:
A. 60°
Step-by-step explanation:
From the diagram, in triangle ABC,
AB=BC=CA=15 units.
This means triangle ABC is an equilateral triangle.
All angles in equilateral triangle are congruent. The sum of all interior angles in triangle is always 180°, so one angle of equilateral triangle is equal to 60°. Thus,
∠A=∠B=∠C=60°
