Answer:
-16/45
Step-by-step explanation:
8/15 x (-2/3)
multiplying a positive and a negative equals a negative
-8/15 x 2/3
multiply the fractions
-16/45
Rewrite the expression on the left using the distributive property
Answer:
x = 20/33
Step-by-step explanation:
-6.6x = -4
Divide both sides by -6.6.
x = -4/(-6.6)
x = 40/66
x = 20/33
Answer:
1)B:63°
2)A:59°
Step-by-step explanation:
1.ABC is a right triangle at C then angle ACB=90°(right angle)
Angle CAB=27°(see the given)
measure of the angles in any triangle is 180°
then angle CBA=
measure of all the angles - (measure ACB+measure CAB)
=180°-(90°+27°)
=63°
2. Same explanation of angle B:
in the right triangle DEF: angle DEF=90°
angle D=31°(given)
Then measure of angle A=180°-(angle E + angle D)
=180-(90+31)=59°
Answer:
A triangle is normally 180 degrees only.
Step-by-step explanation:
So, you have one 90 degree angle, and on 42.7 degree angle. Add those up to 132.7. Now, you would subtract that from 180, meaning that the answer is A, 47.3.
Good luck :DD
