The answer is C, good luck
Answer:
x=90° and y= 43°
Step-by-step explanation:In ∆ABC Applying
Angle sum property
47°+47°+2y=180°
y=43°
In ∆ABD Applying Angle sum property
x=90°
Answer:
Step-by-step explanation:Step 1: Simplify both sides of the equation.
−2+3y=y−2−4y
−2+3y=y+−2+−4y
3y−2=(y+−4y)+(−2)(Combine Like Terms)
3y−2=−3y+−2
3y−2=−3y−2
Step 2: Add 3y to both sides.
3y−2+3y=−3y−2+3y
6y−2=−2
Step 3: Add 2 to both sides.
6y−2+2=−2+2
6y=0
Step 4: Divide both sides by 6.
6y
6

Answer:
y=0
You have coordinates of tree T(16,21) and of rock R(3,2). Let S be a point that denotes treasure. Since treasure is buried so that it partitions the distance between a rock and a tree in a 5:9 ratio, you can state that
Find the coordinates of these vectors:
Then
and 
Solve these two equations:
1.
2.
Answer: the treasure are placed at point (7.6,8.8), so the correct choice is B.
It helps to draw diagrams when working through problems like this.
Given a rectangular prism (the suitcase), drawing a diagonal through its side will give you two right triangles. You can use the Pythagorean Theorem (a² + b² = c², where c is the hypotenuse of a right triangle) to find the length of the unknown side. The hypotenuse of the triangle is the diagonal since it is the longest side, and it is opposite the right angle.
a² + b² = c²
a² + 24² = 26²
a² + 576 = 676
a² = 100
a = 10 in
Remember that this is only the side length of the triangle. To find the amount of material needed to cover one side of the suitcase, we need its area. We can find the area using the formula for area of a rectangle: A = bh.
A = bh
A = 10*24
A = 240 in²
