Answer:
y=60° b=60°
Step-by-step explanation:
the sum of all degrees of interior triangle is 180
in the first one, 30° and 90° have been given.(that small square represent 90°)
so 180°-90°-30°=60°
in the second one, the 120° is on the other side of a line, a line has a degree of 180, therefore the interior angle is 60°, the same rule 180°-2*60°=60°
Solve the equation to get values for x and y.
For example,
When x is 0,
y = 1
You have one point on the line (0,1)
Now, when y = 0,
x = 36/5 = 7.2
You have one more point on the line (7.2,0)
Plot these points on the x and y axes.
Draw a straight line joining these two points. ( I hope you can plot the points)
Combine like terms.
4. 5x+9y+3x-2y
8x+7y
7. 22u-6u+4t+4t-8u
8u+8t
10. 23m+4n-3m
20m+4n
The altitude is 6/4 but originally it’s 16 hope this helps ;)
