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
Answer:
96cm
Step-by-step explanation:
If the width is x then length is 2x
so,
x+x+2x+2x=288
6x=288
x=48
length is 48cm
Answer:
One:225
Tenth: 225.2
Hundredth: 225.29
Step-by-step explanation:
In pretty sure this is right i apologize if not I havent done this in a couple of years.
The pattern is adding together the two previous numbers.
6+18=24, and 18+24=42, so the next step is to add 24+32 which equals 56, so the next number is 56
