Sum of internal angles of any triangle = 180∘
∴x + 2x + 3x = 180∘
∴6x = 180∘
∴ x = 30∘
So the angles are: 30∘, 60∘ and 90∘
Answer:
Step-by-step explanation:
<u>We see that:</u>
- y- intercept is b = 0.5, point (0, 0.5)
- Rate of change is m = 1 as each next value of y is greater by 1.
<u>The function is:</u>
Correct choice is A
Answer:
18000$
Step-by-step explanation:
Frim the text you have the formula:
V=c-crt
where,
c=30000
r=0.1
t=4
So, new value after 4y:
V=30000-4*0,1*30000=30000-12000=18000
