Can anyone please help me
STatiana [176]

Answer:

42°

Step-by-step explanation:

Sum of all the angles inside of any triangle is always 180°.

Therefore:

180 = y + 90 + 48

y = 180 - 90 - 48

y = 42°

How do you find your y-intercept from your x-y points?
PSYCHO15rus [73]
1. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. ...

2. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

3. To find the y-intercept, set x = 0 \displaystyle x=0 x=0.

Solve ax-5=b for a. So which one is right A,B,C or D
Darya [45]
It would be c

ax-5=b What you have to do is get a to be by itself

So you would add 5 to both sides:
ax-5(+5)=b(+5) = ax=b+5

And then divide x by both sides. You divide because a is multiplied by x on the left side, so to move it to the other side you’d have to do the opposite and divide:
ax /x=b+5 /x

Answer is C ... a=(b+5) /x
