Answer:
26, 68 and 84
Step-by-step explanation:
Let the angle that is three times smaller than another be X.
Since the angle sum of a triangle is 180 degrees, we can form the following equation:
X + 3X + (3X- 16) = 180
Now we can simplify this equation:
7X - 16 = 180
7X = 196 (add 16 to both sides)
X = 196/7
X = 28
Therefore, the smallest angle is 28 degrees.
And from here we can figure out the other angles as they are 3x28 and 3x28 - 16.
So the three angles are 28 degrees, (3x28-16) 68 degrees, and (3x28) 84 degrees.
-5b2+10b+10b=120
-5b2+20b=120
-5b(b-4)=120
b-4=-24b
-b-24b=-4
-b(1-24)=-4
b=0.173913043478261
Answer:
BCD = ECD
Step-by-step explanation:
they would equal the same thing because it is still the same shape
Answer:
ok 4 ways
Step-by-step explanation:
1.add 5+4=9
if not
2.4-5=-1
if not
3. 4x5=20
if still not then
4. 4/5=0.8
hope that helps
C. 2:3 because the original ratio is 12:18, but to complete this ratio you would need to simplify the ratio to 2:3.
