Answer:
x = 60°
Step-by-step explanation:
since, the triangles are complementary the sum of their measures will be 90°
now,
The answer is 364 I think .
Answer:
a = 8 (to nearest whole number)
Step-by-step explanation:
Given:
m<B = 36°
m<C = 104°
c = 12
Required:
a
SOLUTION:
✔️First find m<A:
m<A = 180 - (104 + 36)
m<A = 40°
✔️Find a using Sine Rule:
Thus:
Plug in the values
Multiply both sides by sin(40)
(nearest whole number)
Answer:
a) 2,650%
b) 27,400%
c) 164,900%
Step-by-step explanation:
We want to measure the percentage we would have to increase the typical value to obtain the values given in a), b) and c).
But 0.2 increased in x% equals
0.2 + 0.2(x/100) =0.2(1+x/100)
So, if we want to increase 0.2 in x%, we must multiply it by (1+x/100)
a)
We need to find the value of x such that
0.2(1+x/100) = 5.5 ⇒ (1+x/100)=5.5/0.2 ⇒ 1+x/100=27.5
⇒ x/100=26.5 ⇒ x=2,650%
b)
0.2(1+x/100) = 55 ⇒ (1+x/100)=55/0.2 ⇒ 1+x/100=275
⇒ x/100=274 ⇒ x=27,400%
c)
5.5 min = 5.5*60 s = 330
0.2(1+x/100) = 330 ⇒ (1+x/100)=330/0.2 ⇒ 1+x/100=1,650
⇒ x/100=1,649 ⇒ x=164,900%
Yes, the two ratios are equivalent. If you multiply both the numerator and the denominator by 6, you will get 18/42.
