Answer:

A is the correct answer.

Step-by-step explanation:

- B, C, and D are wrong because those only move the position of the shape, which means they are still congruent.

- 1/7x means the shape will get smaller and therefore not be congruent.

- Congruent means they have the same size and shape. All have the same size and shape, but A and therefore that is the correct answer pertaining to this problem.

- Hope this helps! if you need a further explanation or help on any other problems please let me know. I would be glad to help anytime.

Circuit Training If sin0 =1 and 0 <0< π find 0.

valkas [14]

Answer:

$\theta = \frac{\pi}{2}$

Step-by-step explanation:

Given

$\sin(\theta) = 1$

$0 < \theta < \pi$

Required

Find $\theta$

$0 < \theta < \pi$ implies that $\theta$ is between 0 and 180 degrees

$\sin(\theta) = 1$

Take arcsin of both sides

$\theta = sin^{-1}(1)$

This gives:

$\theta = \frac{\pi}{2}$

Convert to degrees

$\theta = \frac{\pi}{2} * \frac{180}{\pi}$

$\theta = 90$

We have:

$0 < \theta < \pi$ or $0 < \theta < 180$

To get other values of $\theta$

We use:

$\sin(\theta) = \sin(180 - \theta)$

Substitute: $\theta = 90$

$\sin(90) = \sin(180 - 90)$

$\sin(90) = \sin(90)$

This means that there are no other values of $\theta$ in the given range

A snake tank measures 1.8 m x 0.5 m x 0.5 m. What is the surface area of the tank including the top? Use the formula: SA = 2hl+2

olganol [36]

Answer:

4.1

Step-by-step explanation:

1.8 x 0.5 = 0.9

0.5 x 0.5 = 0.25

2(0.9 + 0.9 + 0.25) = 2(1.8 + 0.25) = 2(2.05)

2 x 2.05 = 4.1

Therefore the answer is 4.1

I hope that was helpful!

NO LINKS!!! Find the measurement indicated. Round your answer to the nearest tenth.

My name is Ann [436]

Answer:

Solutions given;

Using cosine rule

b²=a²+c²-2*a*c*cos B°

b²=15²+8²-2*15*8*cos39

b²=102.48

b= $\sqrt{102.48}$

b=10.12

b=10.1

Using sine rule

$\frac{sin A}{BC} = \frac{sin B}{AC} =\frac{sin C}{AB}$

$\frac{sin 29°}{15} =\frac{sin C}{8}$

Doing criss cross multiplication

Sin C= $\frac{sin 29°}{15} ×8$

m<C=Sin -¹(0.29)

m<C=14.98

m<C=15°is a required answer.
