You can see that the two small angles are close to the 43 degree angle they are both acute while the other is obtuse. Now i'm only in Tenth grade and i read certain letters backwards so i may mix you up but i'ma try.
B should be a 40 degree angle or lower i dont know i dont have my protractor when i need it.
i cant give you the other two cause its too blury to read

Answer:
a. 3x = 45
15cm
Step-by-step explanation:
Given the perimeter of an equilateral triangle = 45cm .
Using the equation
3x = 45
Divide both sides by 3
x = 45/3
= 15cm
The length of each side of the triangle is 15cm because an equilateral triangle has its three sides equal
Answer:
y = -3x
Step-by-step explanation:
the equation of the line would follow the formula y = mx + b, where m is the slope and b is the y-intercept. the slope is -3 so we would substitute that in for m. and since there is no y-intercept in this situation, our equation would be y = -3x.
i hope this helps :)
