Answer: +23
Step-by-step explanation:
It would be 23 because the difference between -19 and 4 is 23
Answer:
Step-by-step explanation:
Remark
The ratios are certainly correct but that doesn't mean that they show similarity. SSA is a very dangerous proposition to use. Redraw triangle DEF of that DF is going to upwards to your right hand side. Make E as it was before. Why isn't this right?
It isn't right because E has gone from being an acute angle to an obtuse angle (an angle larger than 90 but less than 180).
The ratios are still true, but the angles do not match. So the whole answer is incorrect.
Answer:
I thinks its r = 11
Step-by-step explanation:
So you just need to take the number to the r and multipliy it by r So,
9x2=18
then minus it by the other number which would Be 7 so.
18-7=11
Answer:
15
Step-by-step explanation:
So angle 2 and angle 4 have a relationship that is called same-side interior or consecutive interior angles. The name there depends what class you are in but they mean the same thing.
If you have the transversal goes through parallel lines, then same-side interior angles will add up to 180 degrees.
So you are trying to solve the following equation for x:
angle2+angle4=180
2x+10+4x+80=180
Combine like terms:
6x+90=180
Subtract 90 on both sides:
6x =90
Divide both sides by 6:
x =90/6
Simplify:
x =15
15 is x so that the lines are parallel
