Pls help if you can,,,,

Mathematics
1 answer:
s2008m [1.1K]3 years ago
3 0

Answer:

Step-by-step explanation:

All the angles in a construction like this one are either 7x or 11x. In this case the acute angle is 7x and the obtuse angle  is 11x

11x + 7x = 180

18 x = 180

x = 10

So 7x = 7 * 10 = 70

11 x  = 11 * 10 = 110

Part C

The relationship is that the acute angle + the obtuse one = 180

Aneli [31]

Answer:

Step-by-step explanation:

Find the value of the left hand side (LHS)

LHS = 1/4 // 5/6

LHS = 1/4 * 6/5

LHS = 6/20

LHS = 3/10

Now what will make 3/10 on the right?

B:  1/4  * 6/5 = 6/20 = 3/10

a = 4

b = 6

If tan e = 1.3, what is the value of cot (90° - 9)?
ella [17]

Answer:

A

Step-by-step explanation:

We are given that:

\tan(\theta)=1.3

And we want to find:

\cot(90^\circ -\theta)

Remember that tangent and cotangent are co-functions. In other words, they follow the cofunction identities:

\tan(\theta)=\cot(90^\circ-\theta)\text{ and } \cot(90^\circ-\theta)=\tan(\theta)

Therefore, since tan(θ) = 1.3 and cot(90° - θ) = tan(θ), then cot(90° - θ) must also be 1.3.

Our answer is A.
