This equation involves no x variable, so I assume you want to solve this for D.
First of all, you can divide both sides by 0.785 to get
Since the right hand side is positive, the equation make sense (otherwise we would be asking a square, i.e. a positive number, to equal a negative number). So, we can extract the square root from both sides:
Answer:
3/80
Step-by-step explanation:
Angle z makes a 180° angle when added to the angle of 124° in the first image, because they are on the same side of a straight line. Just subtract 124 from 180. =56
For the second picture, angle m will be the same as angle z because of the properties involved. Find angle z using the same thought process as above, and m will equal it. =55
The sum of the angles in a triangle is 180°, that's just a property they have. You add the two angles you know, subtract them from 180, and you have x. =47
Answer:
A trapezoid is a quadrilateral with exactly one pair of congruent sides.
Step-by-step explanation:
Hello!! So any time a question says "What percent" you can immediately write down the fraction X/100. The proportion would be 15/20= x/100. Then cross multiply to get the equation 1,500=20x. Divide both sides by 20 and x equals 75! Hope this helps!
