Answer:

77.7 °

Step-by-step explanation:

So this uses the sum of interior angles, which in a rectangle, is 360°.

Now, we have two regular right angles, in the top and bottom right corners. Those angles measure 90° each. 90° + 90° = 180°.

Now we got the top left corners angle, so all that is left to do, is to subtract the three given corners angles, and the remaining is the angle for x.

So: 360° - 180° - 102.3 = 77.7°

So angle x = 77.7° :)

Hope this helped a bit!

If two angles are supplementary and one of the angles measures 38°, what is the measure of the larger angle?

il63 [147K]

Answer:

142°

Step-by-step explanation:

Supplementary angles by definition are two or more angles that add up to 180°. So we must find out 180°-38° to get the missing angle which is 142°

Hope this helped!

Please help me with these two questions, 10 points for each so in total 20!!

saul85 [17]

Answer:

$\large\boxed{Q2.\qquad C.\ -2x+y=-2}\\\boxed{Q4.\qquad C.\ y=3x+12}$

Step-by-step explanation:

Q2:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (4, 6) and (6, 10). Substitute:

$m=\dfrac{10-6}{6-4}=\dfrac{4}{2}=2$

$y-6=2(x-4)$ use distributive property

$y-6=2x-8$ add 6 to both sides

$y=2x-2$ subteact 2 from both sides

$-2x+y=-2$

Q4:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

Put the slope m = 3 and the coordinateso f the point (-2, 6) to the point-slope form of an equation of a line:

$y-6=3(x-(-2))$

$y-6=3(x+2)$ use distributive property

$y-6=3x+6$ add 6 to both sides

$y=3x+12$
