Answer:
9
Step-by-step explanation:
To find the area of a triangle where you know the x and y coordinates of the three vertices, you'll need to use the coordinate geometry formula: area = the absolute value of Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By) divided by 2. Ax and Ay are the x and y coordinates for the vertex of A. The same applies for the x and y notations of the B and C vertices.
Fill in the numbers for each corresponding letter combination within the formula.
Fill in your formula like this: 0(8-10) + 3(0-0) + 9(0-8).
Subtract the numbers within the parentheses.
0 from 8 = 8, 0 from 0 = 0 and 8 from 10 = 2.
Multiply that result by the number to the left of the parentheses.
0 by 8 = 0, 3 by 0 = 0 and 9 by 2 = 18.
Add the three products together.
0 + 0 + 18 = 18
Divide the sum of the three products by 2.
18 ÷ 2 = 9

the actual answer is B.) 4
Step-by-step explanation:
just took the topic test
Answer:
2/3 1 4/3 and 5/3
Step-by-step explanation:
just multiply 1/3 with any whole number.
Statement 3:
NO and ON are the same line. They are congruent by the reflexive property (a line segment is a reflection of itself).
Statement 4:
Shape MNO and shape PON are congruent by side-side-side since:
side PN = side MO
side MN = side PO
side NO = side ON
Answer: Fourth option
The measure of angle D to the nearest tenth of a degree is 47 degrees
<h3>Application of SOH CAH TOA</h3>
This theorem is used to determine the measure of sides and angles of a triangle.
According to the theorem
tan theta = opp/adj = 1.055
theta = arctan(1.055)
theta = 46.53 degrees
Hence the measure of angle D to the nearest tenth of a degree is 47 degrees
