Suppose measure of angle ABC equals 110, what is the measure of angle DBC?

1 answer:

8 0

There is no way of solving that unless we are given more information. Are ABC and DBC supplementary angles? If so, then m<DBC equals 70.

Divide $2769 by $9 and you get 306.6 but you can’t just buy .6 of a toy so that leaves you at 306 whole toys and 306x9 is $2754 so you would have $15 leftover

X=4y-7 2x+9y=-31 What be the answer

dybincka [34]

Answer:

x=-11

y=-1

Step-by-step explanation:

x=4y-7

2x+9y=-31

2(4y-7)+9y=-31

8y-14+9y=-31

17=-31+14

17y=-17

y=-1

x=4(-1)-7

x=-11

WILL GIVE BRAINLIEST IF CORRECT ANSWER!!!

Rom4ik [11]

Answer : 2√3

Given :-

A equilateral triangle with side length 4.

To Find :-

The value of x in the given figure.

As we know that in a equilateral triangle , perpendicular bisector , angle bisector and median coincide with each other .

So the perpendicular drawn in the figure will bisect the given side .
Therefore the value of each half will be 4/2 = 2 .

Now we may use Pythagoras theorem as ,

→ AB² = BC² + AC²

→ 4² = 2² + x²

→ 16 = 4 + x²

→ x² = 16-4

→ x² = 12

→ x =√12 = √{ 3 * 2²}

→ x = 2√3

Hence the required answer is 2√3 .

I hope this helps.

Use complete sentences to describe why postulates are helpful?

Savatey [412]

Postulates are helpful because it helps you plan and solve geometry problems.
That's my guess. It doesn't tell me in the text either.
