Answer:

b) 20

Step-by-step explanation:

Here m∠C = 90, It is a right triangle.

So we can use the Pythagorean theorem.

b = √(c^2 - a^2)

Given: a =21 and c = 29. Now let's plug in these values in the above formula, we get

b = √(29)^2 - (21)^2

b = √(841 - 441)

b = √400

b = 20

Therefore, the side length b = 20.

Hope this will helpful.

Thank you.

Answer:

The correct option is 1.

Step-by-step explanation:

Given information:∠C = 90°, side c = 29, and side a = 21.

In a right angled triangle, the opposite side of right angle is hypotenuse.

Since angle C is a right angle, therefore ABC is a right angled triangle with hypotenuse c=29.

According to Pythagoras theorem,

(hypotenuse)^2=(leg_1)^2+(leg_2)^2

Using Pythagoras theorem, we get

(c)^2=(a)^2+(b)^2

(29)^2=(21)^2+(b)^2

841=441+(b)^2

841-441=(b)^2

400=(b)^2

Taking square root on both the sides.

\sqrt{400}=b

20=b

The value of b is 20 , therefore the correct option is 1.

Simplify:<br> 2(xy - 7) = [?]<br> x = -1 and y = 3
fiasKO [112]

Answer:2(xy-7)= -20

Step-by-step explanation:

Plug in -1 for x and 3 for 3, as the question says that x and y represent those values.

2(xy-7) = ?

2((-1)(3) - 7) = ?

2(-3-7)=?

2(-10)

-20

2(xy - 7) = -20

In the diagram, m angle SUR =32 degrees. Find mRS and m angle STR.
igomit [66]

Because SUR=32, then RS must be 32 and because STR=64. You could also tell this because the shape in the circle is not perfectly symmetrical
