Answer:
70 degrees.
Step-by-step explanation:
Hello!
It says that this triangle is a right triangle. That means one angle is 90°. Since there are 180° in a triangle, all we have to do is subtract 90 + 20 from 180.
90 + 20 = 110
180 - 110 = 70.
So the medium angle is 70°.
Hope this helps!
Answer:
- r=3
Step-by-step explanation:
Given the sequence
The common ratio is determined by the division of term by the previous term.
Common Ratio, 
A recursive formula is a formula that defines each term of a sequence using preceding term(s).
For the given sequence, the recursive formula is:
Add the two rows together
3x = 12
Solve for x in the above equation
x = 4
Substitute x = 4 into any of the two equations above. Let's choose the first one; 2x - y = 6
2 × 4 - y = 6
Solve for y in the above equation
y = 2
Thus,
<u>x = 4</u>
<u>y = 2</u>
