Answer:
∠B
7(13)-1=90˚
Step-by-step explanation:
Are you saying ∠ABC or ABC as sides?
1. ∠ABC
(7x-1)+(4x+1)+(3x-2)=180˚
14x-2=180˚
14x=182
x=182/14
x=13˚
2. plug in
∠A
4(13)+1=53˚
∠B
7(13)-1=90˚
∠C
3(13)-2=37˚
Answer:
12x + 4
Step-by-step explanation:
ok so a rectangle has 4 sides, 2 of which are called lengths, and 2 of which are widths.
length = 2x-3
width = 4x+5
the perimenter is the total of the 4 sides.
2(2x-3) = 4x-6 (the total for lengths)
2(4x+5) = 8x+10 (the total for widths)
add the 2 together:
12x+4
Answer:
see the explanation
Step-by-step explanation:
we know that
In a Rhombus opposite angles are congruent and consecutive angles are supplementary
The diagonals are perpendicular and bisect the angles
so
step 1
Find the measure of angle 4
we know that
--->by the diagonals bisect the angles
step 2
Find the measure of angle 1
we know that
----> by opposite angles are congruent
step 3
Find the measure of angle 2
we know that
----> by the diagonals bisect the angles
so
step 4
Find the measure of angle 3
we know that
----> by the diagonals are perpendicular
step 5
Find the measure of angle 5
we know that
----> by complementary angles
step 6
Find the measure of angle 6
we know that
----> by the diagonals bisect the angles
Answer:
1/3.
Step-by-step explanation:
The slope of the given line = (-4 - -7)/(2-3)
= 3 / -1
= -3.
The line perpendicular to this has slope - 1 / (-3)
= 1/3.
Answer:
20
Step-by-step explanation:
you first multiply 7 and three
then add that to four
then subtract 5
