If angle BCD measures 70° then so does angle DBC (because you have formed an isoceles triangle inside the larger ΔABC and the two legs are equal so the two angles have to be equal. So we have a two 70° angles which leaves 40° for the 3rd angle, which is ∠BDC.
Since ∠BDC and ∠ADB are supplementary (180°) - that leaves 140° for ∠ADB and is our answer
Step-by-step explanation:
-2a + x
Putting values of a = - 2 and x = 7
-2(-2) + 7
4 + 7
= 11
Answer: 6 ounces
Explaintion: 24 minus 18 equals 6
This will be an obtuse angled triangle because one angle is greater than 90 degrees.
$8250 - $3120 = $5130
$5130/75 = $68.40
Each band member must raise $68.40
