Answer:

x=28

Step-by-step explanation:

We know a triangle equals 108 degrees. B is a right angle so that's 90 degrees. 180-148 will give us C. C is 32 degrees So we know 2 angles, to find the third add the 2 angles (122) and create the equation 2x+2+122=180 simplify to get x=28

Hope this helped :D

Answer:

Correct answer is x = 28°

Step-by-step explanation:

Okay we know Angle A is 2x + 2

Angle B is 90

Angle C is 180 - 148 = 32 ( straight line angle is 180)

Sum of all angles should be 180 in a triangle

which means

A + B + C = 180

2x + 2 + 32 +90 = 180

2x + 124 = 180

2x = 180-124

2x = 56

x = 56/2

x = 28

The figure is a parallelogram.one diagonal measures 28 units. Is the figure a rectangle? Explain

guajiro [1.7K]

Answer:

The parallelogram is not rectangle because the sides of the parallelogram do not meet at right angles.

Step-by-step explanation:

Given the parallelogram with sides 20 and 21 units with diagonal length 28 units.

we have to tell it is a rectangle or not.

The given parallelogram is rectangle if the angle at vertices are of 90° i.e the two triangle formed must be right angles i.e it must satisfy Pythagoras theorem

$28^{2}$ = $20^{2}$ + $21^{2}$

784=400+441=881

Not verified

∴ The sides of the parallelogram do not meet at right angles.

Hence, the parallelogram is not rectangle because the sides of the parallelogram do not meet at right angles.

Hope it helps

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 50, 60,72,... Find the 8th term.

Vadim26 [7]

Answer:

179.159

Step-by-step explanation:

Given the sequence :

50, 60, 72,..

The sequence given is a geometric sequence :

For a geometric sequence ;

ar^(n - 1)

a = first term

r = a2 / a1 = 60 / 50 = 1.2

The 8th term ; n =8

a8 = ar^(n - 1)

a8 = 50*1.2^(8 - 1)

a8 = 50*1.2^7

a8 = 50*3.5831808

a8 = 179.15904

a8 = 179.159 (nearest thousandth )

Round 2481.65 to the neartheast 10 tenth

gregori [183]

2481.7

^ is the tenth place.

The 5 would either round it up or down by one-tenth. Since we like big numbers... we'll round it to 7 from 6.
