Answer:
X=-7
Step-by-step explanation:
X + 142=135°
X=135-142
X=-7
So the value of X is -7
<span>(2.2 × 1012) + (1.7 × 109) = 2411.7</span>
Answer:
8 boxes approx
Step-by-step explanation:
Step one:
given data
One box contains 48 bars
Required
The number of boxes needed for a total of 338 students if each person is to get at least one bar.
Step two:
this can be gotten by dividing 338 by the number of the bar in a box
= 338/48
=7.04
=8 boxes approx
He needs to purchase at least 8 box
Same-side interior angles, which are shown here, are supplementary, which means that they add up to 180 degrees.
5a + a = 180
6a = 180
a = 30 degrees
Hope this helps! :)
Answer:
x = 34
Step-by-step explanation:
ΔABD and ΔBCD are both isosceles triangles
In ΔABD
AB =AD, hence ∠ABD = ∠ADB ( base angles are equal )
∠ABD = 
= 
= 68°
∠DBC = 180° - 68° = 112° ( straight angle )
∠BCD = x = 
= 
= 34
