Answer:
145°
Step-by-step explanation:
upper left angle inside triangle is 180-137, or 43°
lower right angle inside triangle is 180-(43 + 102) or 35°
'?' measures 180 - 35 which is 145°
Quadrilateral RICE is a rectangle because the lengths of the quadrilateral have 2 sides congruent to each other. Also, RICE has slopes with opposite fractions which make the sides parallel to each other.
To find n
1. Subtract 8n from both side to get -3n=30
2. Divide both sides by -3 to get n=-10
Answer:
Step-by-step explanation:
The given system is
3x-2y=6
0.4(20y+15)=x
The slope intercept form is y=mx+c.
For the first equation, 3x-2y=6, we add -3x to both side -2y=-3x+6
For 0.4(20y+15)=x, we expand to get:
Divide through by 8
Therefore the system in slope-intercept form is:
