<span>If you know 2 sides and an included angle, the area formula is:
</span>
<span>Area = ½ • side 1 • sine (A) • side 2
</span>
<span>Area = ½ • 2 * sine (60) * sq root (2)
</span>
<span>Area =sine (60) * sq root (2)
</span>
<span>The sine of 60 degrees = sq root (3) / 2
</span>
Area = sq root (6) / 2
Answer:
In photomath
Step-by-step explanation:
1.) 6p-12 or 6(p-2)
2.) -4n-3
3.)-58-55b
4.) 22-41p
5.)8(3n-5) or 24n-40
6.)-2(2x+3) or -4x-6
Answer is the last choice
2a-4/1= -a-1/a-4
Cross multiply
(2a-4)(a-4)= -(a-1)
2a^2-8a-4a+16= -a+1
Bring right to left sign change signs
2a^2-8a-4a+16+a-1=0
Combine like terms
2a^2-11a+15=0
a= 2 b= -11 c= 15
Use quadratic formula
-b+-sq rt of b^2-4ac. Divided by 2a
-(-11) +- 11^2-4(2)(15) divided by 2(2)
11+-sq rt 121-120 divided by 4
11+1 /4. 11-1/4
12/4. 10/4
3. , 5/2
The answer is
