The answer is B..........................
Answer:
13 1/2
Step-by-step explanation:
9*3/2=13 1/2
"E" stands for exponent, specifically 10. If something says "E+38" (like in Microsoft Excel), that means 10^38 in scientific notation.
Therefore, "-3.4 E + 38" means -3.4x10^38.
The "+38" means there are 38 zeros following a 1 as the exponent. It also works with negative numbers. For example, E-3 equals 10^-3
Answer:
200 degrees.
Step-by-step explanation:
By theorem of inscribed angle...
The measure of an inscribed angle is half the measure of the intercepted arc. [Theorem]
therefore, m(angle J) = half of m(arc CDE)
therefore, m(arc CDE) = 2 * m(angle J)
therefore, m(arc CDE) = 2 ( 100)
therefore, m(arc CDE) = 200 degrees.
Answer:
106º
Step-by-step explanation:
In an isosceles trapezoid, there are two sets of cungruent angles. Multiply 74*2=148.
All quadrilaterals have interal degrees that add up to 360º. Use 360-148=212 to find the value of remaining angles. Since the angles are congruent, divide by 2.
212/2=106.
Check by adding all angels.
74+74+106+106=360✔️
