Answer:
solution :
in the given figure AB=10.2cm, AC=14cm, AD=DC and AD perpendicular to BC.
now ,
in rt angle tirangle ADC,
angleACD=45 degree, angle DAC=45 degree now,
in triangle ABD,
angle BAD+angleABD+angleADB=180 DEGREE (sum of the sngle of triangle)
angle BAD+75+30=180
angle BAD=180-165 therefore,angle BAD=15
angle BAC =15+45=60
Area of triangle ABC=1/2×AB×AC×SIN 60
=1/2×10.2×14×√3/2
=61.83cm³ ans
16 whites $191.20 and 17 yellow $195.50 total $386.70
Answer:
SU=25
Step-by-step explanation:
We can set up a ratio as STU and SQR are similar because of the SAS similarity theorem.
TQ:SQ
SQ=ST+TQ=10+6=16
6:16=3:8
Therefore the ratio of STU:SQR is 3:8
We can use this to find SU
UR:SR=3:8
15:SR=3:8
Cross multiply
3SR=120
SR=40
SU=SR-UR
SU=40-15
SU=25
Answer:
$130
Step-by-step explanation:
Renting the dvd for one day costs $10.
$15 is charged for every late day .
Timmy rented the DVD player for 4 days and returned it 10 days later.
For 4 days , the amount
= $10 x 4
= $40
For the remaining six days he’ll pay
$15 x 6= $90 because he was charged the late fee .
Therefore, total amount paid by Trimmy
= $40 + $90
= $130
Trimmy paid $130
