Answer: 18
Step-by-step explanation: -36 / -2 simply
we know angle RLP= 100⁰
also
angle RLP+ angle RLB=180⁰(Linear pair)
=>100⁰+angleRLB= 180⁰
=> angle RLB=80⁰
since BR and LR are equal, angle RBL and angle RLB are equal
therefore angle RBL is also equal to 80⁰
using angle sum property of triangles we know that the sum of all angles in a triangle is equal to 180⁰
=>angle BRL+angle RBL+angle RLB= 180⁰
=> angle BRL+80⁰+80⁰=180⁰
=>angle BRL = 180⁰-160⁰
=>angle BRL= 20⁰
I'm sorry it took me some time I'm a slow typer
Geo is
an=a1r^(n-1)
2nd term is 12
4th term is 4/3
a2=a1r^(2-1)=12
a2=a1r=12
a4=a1r^(4-1)=4/3
a4=a1r^3=4/3
we have
a1r=12 and a1r^3=4/3
(a1r^3)/(a1r)=r^2=(4/3)/12=1/9
1/9=r^2
sqrt oth sides
1/3=r
the common ratio is 1/3
Huh?? I’m confused about the question
Answer:
CB = sqrt62
Step-by-step explanation:
The pythagorean theorem will help with this! First take triangle ACD, AD^2 + CD^2 = AC^2. Plug in, AD^2 + 16 = 25. AD^2 = 9. AD = 3. I'm not exactly sure how to find DB, but I can assume it's double of AD< so 6. We know CD is 4, so 4^2 + 6^2 = CB^2. 16 + 36 = CB^2. CB = sqrt62
Sorry if this isn't exactly right, there's no exact way to find DB.
