Answer:
The measure of angle G is
Step-by-step explanation:
Let
F ----> the measure of interior angle F of the triangle FGH
G ---> the measure of interior angle G of the triangle FGH
H ---> the measure of interior angle H of the triangle FGH
we know that
The sum of the interior angles in a triangle must be equal to 180 degrees
so
----> equation A
----> equation B
----> equation C
Solve the system of equations by substitution
substitute equation B and equation C in equation A
Solve for F
Find the measure of angle G
substitute the value of F
Answer: The length of JF = 16 units.
Step-by-step explanation:
Given: In triangle DEF, segment DJ is a perpendicular bisector of side EF.
i.e. DJ is perpendicular to EF and DJ divides EF into two equal parts EJ and JF. [The perpendicular bisector is a line that is perpendicular to a line segment and splits it into two congruent segments.]
If EJ is 3y-8 and JF is 7y-40.
Then,
JF= 7(8)-40 =56-40= 16 units
Hence, the length of JF = 16 units.
Step-by-step explanation:
f(x)=(30x-2)
then,
f(3)=(30×3-2)
=90-2
=88 hope so,
