Answer:
a. 156°
Step-by-step explanation:
The marked angle at P is the average of the arcs intercepted:
((13x)° + (5x+10)°)/2 = (10x -7)°
(18x +10)/2 = 10x -7 . . . . simplify a bit
9x +5 = 10x -7 . . . . . . . . simplify more
9x +12 = 10x . . . . . . . . . . add 7
12 = x . . . . . . . . . . . . . . . . subtract 9x
Now, use this value to find (13x)°.
13x° = 13(12)° = 156° . . . measure of arc DC
Answer:
Area is square units so if length is tripled (times 3), area is times 3^2 or 9
so 600•9 = 5400 cm^2
Kind of expression and its example:
Quotient: .
Product: 8b.
Sum:
<u>Step-by-step explanation:</u>
While translating the problems into mathematical expression or mathematical expression in English, Kind of Expression can be used. Mostly in the algebraic parts.
Quotient: It represents that one value is divided by the another value. It is also known as the ratio.
i.e: .
Product: It means multiplying either a known value and unknown variables or both unknown variables.
i.e.: 8b.
Sum: It means adding either a known value and unknown variables or both unknown variables.
i.e.:
THE SLOPE IS -2
if we have the coordinates of two points on a line, we can find the slope with this formula:
so the slope is
the answer is -2
good luck
Consider definitions of <u>parallelogram</u>,<u> trapezoid</u>, <u>rectangle</u>, <u>kite</u> and <u>rhombus</u>.
Parallelogram is a quadrilateral with two pairs of parallel opposite sides.
Trapezoid is a quadrilateral with one pair parallel opposite sides, trapezoid is not parallelogram, so option 1 is false.
Rectangle is a parallelogram with all angles right. Rectangle has diagonals that are congruent. Option 2 is true.
Kite is a quadrilateral with two pairs of congruent adjacent sides. Kite is not parallelogram, so option 3 is false.
Rhombus is a parallelogram with all sides congruent. The diagonals of the rhombus are not congruent, but they are perpindicular bisectors of each other. Option 4 is false.
Answer: correct choice is option 2
