14
Step-by-step explanation:
Area of a triangle = 1/2 ×base ×height
= 1÷2 ×(7×4)
=1÷2 ×28
=14
Answer:
the x would equal to 9
Step-by-step explanation:
21+6=27
27÷3=9
The first operation used is <span>multiplication (2x is 2 times x). </span>
2(P+1)+3(P+2)>2
Distribute
2P+2+3P+6>2
Simplify
5P+8>2
Subtract 8 from both sides
5P>-6
Divide both sides by five
P>(-6/5)
Turn to mixed number and you're done.
P>-1 and 1/5
Answer:
76.53 cm
Step-by-step explanation:
From the question, the triangle formed has 2 sides and an included angle ;
Angle, θ = C = 45°
We use cosine rule :
Taking the side to find as c
a = 100 ; b = 100
From cosine rule :
c = sqrt(a² + b² - 2abCosC)
c = sqrt(100² + 100² - 2(100*100)Cos45
c = sqrt(10000 + 10000 - 20000 * 0.7071067)
c = sqrt(20000 - 14142.135)
c = sqrt(5857.865)
c = 76.536690
c = 76.53 cm
