Answer:
-6
Step-by-step explanation:
Add the positive numbers first which is nine then add a negative like -8 and you get then add -7 which is -6
Smallest angle is °
<u>Step-by-step explanation:</u>
Here we have , Quadrilateral WXYZ has interior angles that meet the following criteria:
Angles W and X are congruent.
According to question , angles are congruent i.e. Both angle measure same
⇒
Now ,
• The smallest angle's measure is 100° less than twice the measure of W.
According to above statement we have ,
Smallest angle =
• The largest angle's measure is 10º more than twice the measure of X. ( correction , in question given as 2X )
According to above statement we have ,
Largest angle =
Now , We know that sum of all 4 angles in 360 i.e.
⇒ { X=W }
⇒
⇒
⇒
Smallest angle is :
Therefore , Smallest angle is ° .
Answer:
Daily points, you have made my day!!!!!!!!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
6 x -9 = -54
<span>6 + (-9) = -3
</span>x2<span> - 3x - 54 = 0
</span>
<span>(X + 6 ) (X - 9)
</span>
x2<span> - 3x - 54 = (X + 6 ) (X - 9)
=
6 & -9
