HELP QUICK!! WILL GIVE BRAINILIST Find the value of x in the triangle shown below.

Mathematics
1 answer:
aev [14]3 years ago
4 0

Answer:

58

Step-by-step explanation:

Since two of the sides are both 6.2, we know that this is an isosceles triangle. Thus, the two angles opposite of x are both equal (61 degrees).

The angles inside of a triangle always add up to 180, so now we have

180 = 61 + 61 + x

Solving for x, we get x = 180 - (61 + 61) = 180 - 122 = 58

Aneli [31]

Answer:

<em>(1, 7) </em>

Step-by-step explanation:

y = 3x + 4

y = 6x + 1

6x + 1 = 3x + 4 ⇒ x = 1

y = 3(1) + 4 = 7

Jose can read 7 pages of his book in5 minutes. at this rate, how long will it take him to read the entire 175-page book?
Lera25 [3.4K]
Since 7 pages could be in 5 min.
So time required by 1 page 5/7 min.
So time required by 175 pages =175×5/7=125 min.
= 2 hours and 5minutes

True or false : <br> 20÷4x5= 1<br> 10+10÷2=15<br> 6+4×5=50<br> 12_3×2=6<br> 81÷9+2=11

To solve, you must use order of operations. The acronym used is BEDMAS (brackets, exponents, division/multiplication, addition/subtraction), which is the order you solve in. 

F  20÷4x5
    =5x5
    =25
      
T   10+10÷2
      =10+5
      =15

F    6+4×5
      =6+20
      =26

<span>T   81÷9+2
     =9+2
     =11</span>

Will some one help me please will friend

Add the equations,just the way they appear there.

-- Add the top 'x' to the bottom 'x'.  Write the sum under the 'x's.
-- Add the '+y' and the '-y'.  Write the sum under the 'y's.
-- Add the '2' and the '4'. Write the sum under them, with n " = " sign
before it.

You should now have an equation with only 'x' in it and no 'y'.
You can easily solve that one and find out the value of 'x'.

Once you know the value of 'x', go back to either one of the original
equations, and plug the number-value of 'x' in place of 'x'.

You'll then have an equation with only 'y' in it and no 'x'.
You can easily solve that one and find out the value of 'y'.
