Answer: 12
Step-by-step explanation:
Answer:
1) x = 60° ; y = 70°
2) x = 50° ; y = 80°
3) x =110° ; y = 60°
4) x =60° ; y = 90°
Step-by-step explanation:
1)
We have to find the interior angle y
= 180 - 120
= 60°
Now we have to find x
=180 - (60 + 50)
= 180 - 110
= 70°
2)
We know that opposite angles are equal
So therfore y = 80°
x = 180 - 80 + 50
x = 180 - 130
x = 50°
3)
According to the figure we see that x+y=180
Exterior angle = sum of two interior angle
So, x = 50 + 60
x = 110°
Now we substitute in the x value
x + y = 180
110 + y = 180
y = 180 - 110
y = 70°
4)
Opposite angles are equal
x = 60°
The figure is a right angle triangle
So,
y =90°

Step-by-step explanation:
Answer:
$10,000 invested in CD
$18,000 invested in money market
Step-by-step explanation:
<u>Complete Question:</u>
<em>Jorge invested $28,000 into two accounts. The amount he put in his money market account was $2,000 less than twice what he put into a CD. How much did he invest in each account?</em>
Let money put in CD be x
So
Money put in money market will be 2x - 2000
Alltogether, that is 28,000. Thus, we can write:
x + (2x-2000) = 28,000
Solving, we get:
x + (2x-2000) = 28,000
x + 2x - 2000 = 28,000
3x = 30,000
x = 30,000/3 = 10,000
$10,000 invested in CD
We know 2x - 2000 invested in money market, so:
2(10,000) - 2000 = $18,000 invested in money market
