Solve for x and y. What is m

1 answer:

4 0

3x + 2y + y - 3x = 180

3y = 180

y = 180/3

y = 60

3x = y - 3x

Let y = 60

3x = 60 - 3x

3x + 3x = 60

6x = 60

x = 60/6

x = 10

Answer: x = 10, y = 60

Using a pencil, pair of compasses and ruler, construct a triangle with sides 8cm, 9cm and 6cm

Sonja [21]

Answer:

The nearest degree of the angle between the 8cm and 9cm sides is:

<u>41°</u>

Step-by-step explanation:

To obtain the correct angle in a small triangle like the triangle formed with the measures in the exercise is a little bit hard, in a change of this, I used a triangle calculator, with this I obtained the right angle formed by the sides with 8 cm and 9 cm, which I'm gonna add like an attachment.

From this image, you can guide yourself to draw the triangle without mistakes and to identify the right angle, which is 40,8° but the compass is not so defined, by this reason you can take it like 41° or 40°.
