Answer:
Step-by-step explanation:
The common difference (d) can be found using the first and 4th terms:
a1 = 3
a4 = a1 +d(4 -1)
-9 = 3 +3d . . . . . simplify
-3 = 1 + d . . . . . . divide by 3
-4 = d . . . . . . . . . subtract 1
Then ...
x = a1 + d = 3 -4 = -1
y = x + d = -1 -4 = -5
The values of x and y are -1 and -5, respectively.
Answer:
<em>36:60:84</em>
<em>A : B : C</em>
<em>36° : 60° : 84°</em>
<em>A= 36°</em>
<em>B= 60°</em>
<em>C=84°</em>
Step-by-step explanation:
<em>3:5:7 =15</em>
<em>180÷15=12</em>
<em>3×12=36</em>
<em>36:x:y =180</em>
<em>5×12=60</em>
<em>36:60:y =180</em>
<em>7×12=84</em>
<em>36:60:84 =180</em>
