Answer:
50.5 degrees
Step-by-step explanation:
Since this is a parallelogram then...
Angle U + Angle R = 180
3x+4+9x-10=180
Combine like terms
12x-6=180
Add 6 to both sides
12x=186
Divide both sides by 12
x=15.5
Now we plug 15.5 in for x to find Angle U
3(15.5)4=46.5+4=50.5
Angle U = 50.5 degrees
Obtuse and isosceles
Isosceles means that at least two of the sides are congruent or equal.
Obtuse means that one angle of the triangle is greater than 90 degrees.
So, your answer is D and E
:)))
Greater than
1/6 x 3/2 = 1/4
1/4 > 1/6
10.3 = 0.6y...divide both sides by 0.6
10.3 / 0.6 = y
17.17 = y <=
Answer:
do you have to add the numbers together or multiply
