Using isosceles triangle theorems solve for x and y
klio [65]
Well lets start by getting y. We already know that all angles of a triangle will equal 180 degrees.
Therefore we know that 65 + 65 + y = 180. To solve for y we just add the two 65's then subtract that from 180
y = 180-130 = 50 Therefore y = 50

Now lets solve for x. We know that since angle B is flat it is equal to 180. The unknown value of angle B = 180 - 65
Therefore that unknown value = 115

As we previously stated all angles of a triangle equal 180. We can now come up with this equation: 115 + x + x = 180
2x = 65
x = 32.5

a b) You are running around a rectangular ground of length 42 m and breadth 24 m. How many metres do you cover when you complete
prisoha [69]

Answer:

792 m

Step-by-step explanation:

perimeter of a rectangle = 2l + 2b

⇒ perimeter of ground = (2 x 42) + (2 x 24) = 132 m

Perimeter = 1 round

⇒ 6 rounds = 6 x 132 = 792 m

3 plus 27 divided by (4 plus 5) Find the sum 1/3 plus 2/5
dezoksy [38]

Answer:

4.) 6

5.) \frac{11}{15}  

Step-by-step explanation:

4.

PEMDAS

Parenthesis, Exponents, Multiplication, Division, Adition, Subtraction.

3 + 27 ÷ ( 4 + 5 )

Do the parenthesis first ( 4 + 5 )

3 + 27 ÷ 9

Do the division next ( 27 ÷ 9)

3 + 3

Now addition.....( 3 + 3)

6

__________________________________________________________

5.

\frac{1}{3} + \frac{2}{5}

In order to find the sum between these 2 fractions, we need to find a common denominator, and in this case, it can be 15...

\frac{1 * 5}{3 * 5} = \frac{5}{15}

\frac{2 * 3}{5 * 3} = \frac{6}{15}

Now that we have a common denominator, we can add them up...

\frac{5}{15} + \frac{6}{15} =\frac{11}{15} \\\\\frac{11}{15}

\frac{11}{15}  is ur answer.

Hope this helped!
