Answer:
<h2>a = 400/21, b = 580/21</h2>
Step-by-step explanation:
Small triangles are similar. Therefore, the sides are proportional
<em>cross multiply</em>
<em>divide both sides by 21</em>
For b, we can use the Pythagorean theorem:
The slope of the line given its equation is calculated through, m = -A / B. The slope of the given line is 4/3. The line perpendicular to it has the slope of -3/4. The slope-point form of the equation is,
y - y1 = m(x - x1)
where m is the slope and x1 and y1 the abscissa and ordinate of the point, respectively.
Substituting the values above,
y --2 = (-3/4)(x - 3)
Simplifying the equation gives 3x + 4y = 1.
Answer:
2
Step-by-step explanation:
Answer:
option B
6
Step-by-step explanation:
Given in the diagram two triangles ABC and DEF,
length of the side AB = 2
length of the side DE = 12
Scale factor of triangle ABC to triangle DEF, is the scale factor of side AB to DE
AB : DE
2 : 12
1 : 12/2
1 : 6
this means triangle DEF is 6 times larger than triangle ABC
or
triangle ABC is 1/6 of triangle DEF
Answer:
Step-by-step explanation:
b = -4 - (8)*(0)
b = -4
y = 8x - 4
