Find the remaining sides of a 30, 60, 90 degree triangle if the side opposite of 60 degrees is 4.

The remaining sides are units and units.

Step-by-step explanation:

It is given that the interior angles of a right angle triangle are 30, 60, 90 degree. The side opposite of 60 degrees is 4.

In a right angle triangle,

The hypotenuse of the triangle is units.

According to the Pythagoras theorem,

Taking square root on both sides.

Therefore, the remaining sides are units and units.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

i think it’s c i believe
