Answer:
∠RST, ∠TSR, ∠S
Step-by-step explanation:
When using three letters, the middle letter must be the vertice of the angle, and the other two are the points surrounding it. You can also just use a single letter to name the angle if there is only one angle at that vertice.
33 in middle - and in between I
Answer:
5
Step-by-step explanation:
Absolute value |x| makes any number positive.
|5| = 5
Answer:
C
Step-by-step explanation:
first we want to find the missing angle at the top
to do that we subtract the given angles by 180
the square indicates that the angle is a right angle or that it equals 90
180-90-40=50
we know that the angle equal to 50 and x are supplementary angles so they will add up to equal 180 so to find x we subtract 50 from 180
180-50-130 so the answer is c
have a great day :D
Answer:
- <u>The total including Tie-nie is 121.</u>
Explanation:
Notice that, since every <em>ancestor</em> has <em>3 parents</em>, the number of ancestors on each previous generation is the result of mulpitlying by 3.
That means that the ratio of the geometric series is 3.
This shows it:
<em>The geometric series is:</em>
- First generation: Tie-nie: 1 = 3⁰
- Second generation, Parents: X, Y, Z: 3 = 3¹
- Third generation, grand parents (G): 3² = 9
- Fourth generation, great-grandparents (GG): 3³ = 27
- Fith generation (GGG): 3⁴ = 81
Hence, the sum is: 1 + 3 + 9 + 27 + 81 = 121
