What is the measure of the missing angle?

Mathematics

MrRissso [65]3 years ago

Answer:

Therefore the measure of the missing angle x, is 90°.

Step-by-step explanation:

Let name the vertices of a Quadrilateral as ABCD such that

∠A = 107°

∠B = 72°

∠C = 91°

∠D = x

To Find:

x = ?

Solution:

In a quadrilateral,

Sum of the measures of all the angles is add up to 360°

\angle A+\angle B+\angle C+\angle D=360\°

Substituting the values we get

107+72+91+ x = 360\\x = 360 -270=90\\\therefore x=90\°

Therefore the measure of the missing angle x, is 90°.

Answer:

Step-by-step explanation:

7*(7 + x+1) = 6*(x + 5 + 6)       {Intersecting secant theorem}

7 *(x + 8) = 6*(x + 11)

Distributive property,

7x + 56   = 6x + 66

Subtract 56 from both sides

7x = 6x + 66 - 56

7x = 6x + 10

Subtract 6x from both sides

7x - 6x = 10

x = 10

ASAP HELP!! CAN SOMEONE PLS HELP ME WITH 20? U HAVE TO USE 18 and 19 to help you!!! THANK U SM!

18) Let x be the number of coins in the pouch:

3x + 3 = 9; subtract 3 from each side:

3x + - 3 = 9 -3

3x = 6 . Now divide both side by 3:

x = 2 (in each pouch we have 2 coins)

19) SAME logic:

4x + 1 = 2x + 7; subtract 1 from each side:

4x + 1 - 1 = 2x + 7 - 1
4x = 2x + 6; now subtract 2x from each side:

4x - 2x = 2x + 6 - 2x

2x = 6   and x = 3 (each pouch contains 3 coins)

5n + 3 = 2(n + 2) + 3n <br> N= ???<br> -Show All Work!-
Gelneren [198K]
Simplifying
5n + 3 = 2(n + 2) + 3n

Reorder the terms:
3 + 5n = 2(n + 2) + 3n

Reorder the terms:
3 + 5n = 2(2 + n) + 3n
3 + 5n = (2 * 2 + n * 2) + 3n
3 + 5n = (4 + 2n) + 3n

Combine like terms: 2n + 3n = 5n
3 + 5n = 4 + 5n

Add '-5n' to each side of the equation.
3 + 5n + -5n = 4 + 5n + -5n

Combine like terms: 5n + -5n = 0
3 + 0 = 4 + 5n + -5n
3 = 4 + 5n + -5n

Combine like terms: 5n + -5n = 0
3 = 4 + 0
3 = 4

Solving
3 = 4
The left and right sides are not equal, therefore there is no solution.
