Answer:
k = 10
Step-by-step explanation:
the sum of any two interior angles is equal to the exterior angle of the unknown interior angle
4k+5 + 6k+10 = 115
10k + 15 = 115
10k = 100
k = 10
Answer:
12
Step-by-step explanation:
n(AUB) = n((A) + n(B) – n(AnB)
Step 1:
Identify the values for each function of the formula. n(A) = 10, n(B) = 5, n(AnB) = 3
Step 2:
Replace each function with its values
n(AUB) = n(A) + n(B) – n(AnB)
n(AUB) = 10 + 5 – 3
Step 3:
Carry on the simple arithmetic
n(AUB) = 10 + 5 – 3 (follow the BODMAS method)
= 15–3
= 12
Therefore, the n(AUB) is 12
c. 1/2
pls mark branliest have a nice day !
the answer is root 5 /3 hope this helps
1. First of all, this is a isosceles triangle, meaning measurement I=58°, which makes it way easier to find T.
1. m{t}°=64 m{I}°=58
2. This one is easy because algebra is the key.
Add like-terms.
x=5
The only thing that confuses me is the y. Is it 7xy, y as a side, or what? Feel free to reply
