Find the value of x need help

Mathematics
1 answer:
amm18123 years ago
5 0

Answer:

x=-10

Step-by-step explanation:

since there's a given 120 degrees, and it's a isosceles triangle, we know that the line adds up to 180 (where the 120 degrees is). so 120+x=180, the interior angle measures 60 degrees. That being said, the 3 angles measure 60 degrees also. now there's a right angle mark on top, so we find the angle of the smaller triangle (near angle 2) by doing 90-60=30 degrees.

angle 2 is said to be x+160, and there's a line, which tells us that they must add to 180.. so x+160+30=180

x+190=180

x=-10.

or, 3- 2c + 8 = 7

or, 11 - 2c = 7

or, -2c =7 - 11

20 POINTS. PLZ HELP!!!!!
liberstina [14]

Answer:

x=27

Step-by-step explanation:

Notice that Angle A is being bisected.

Hence, we can use the Angle Bisector Theorem to write the following proportion:

\frac{x+8}{10}=\frac{2x-5}{14}

Solve for x. Cross-multiply:

10(2x-5)=14(x+8)

Distribute:

20x-50=14x+112

Subtract 14x from both sides:

6x-50=112

Add 50 to both sides:

6x=162

Divide both sides by 6. Hence, the value of x is:

x=27

You made two deposits to your bank account this month. One deposit was $24.61, and the second deposit was $16.49. Your balance a
fenix001 [56]
First you have to find out how much money you have put in this month, so you need to add your two deposits together. 

24.61 + 16.49 = $41.10

Now we know that this month you put $41.10 in your account, but there is a total of $72.31 in your account. Now you need to subtract what you put in this month to your total amount.

72.31 - 41.10 = $31.21 was your balance at the beginning of the month.
