1. 326.73 Its easy, just get the circumference of the circle and multiply it by 9. Then get the area of the circle and multiply that by 2, then add the values together. Cant do 2 or 3 cause I feel like I will get them wrong since I start overthinking it.
Solution:
<u>Note that:</u>
<u>Use the equation above to solve for t.</u>
- 5t - 8 + 68 = 180
- => 5t + 60 = 180
- => 5t = 180 - 60
- => 5t = 120
- => t = 120/5 = 24
The value of t is 24.
Answer:
D
Step-by-step explanation:
Current coordinate of R : ( 1,5 )
Applying translation with rule (x,y) --> (x+1 , y-1)
Coordinate after translation ( 1 , 5 ) ==> ( 1 + 1 , 5 - 1 ) ==> ( 2 , 4 )
applying dilation with scale factor of 3 , to apply dilation multiply x and y values by scale factor which is 3
Coordinate after dilation ( 2 , 4 ) ==> ( 2 × 3 , 4 × 3 ) ==> ( 6 , 12 )
The final coordinate is ( 6 , 12 )
See the attached picture to better understand the problem
we know that
in rectangle ABCD
AB=CD
and
AD=BC
therefore
the triangle ACD and triangle ABC are congruent
so
BD=AC
BD=8 units
the answer part a) isBD= 8 unitsPart b) Find angle CBD
we know that
∠ABD+∠CBD=90°---------> by complementary angles
so
∠CBD=90-∠ABD-----> 90-67----> 23°
∠CBD=23°
the answer Part b) is∠CBD=23 degrees
