Sylvia is correct. This is because the sum of angles in a triangle is 180° and a triangle has 3 angles. If it had 2 right angles (90° each) it would already equal 180° and that's not possible because a thrid angle has to exist.
Hope I helped!

Anna reads 30 in 20 days which means she read 15 chapters in 10 days and di ide 10 by 4 and it 2.5 and add that to 30 and you have your answer
Answer:
y= 5x+4
Step-by-step explanation:
find the slope 34-9/6-1 = 25/5 = 5
then use y-y1= m (x-x1)
y- 9 = 5(x-1)
y-9 = 5x -5
y = 5x +4
the solution is y = 7
Step-by-step explanation:
Given equation is
The equation has to be solved for y
So,
Opening brackets first
Subtracting 8 from both sides
subtracting 8y from both sides
Dividing both sides by -3
so,
the solution is y = 7
