Red Given:
- Length of base is "6cm50mm"
- length of base= 11cm
- Height is "400mm"
- height= 40 cm
Red Solution:
- Area of triangle =1/2bh
- ar.(triangle)=1/2(11cm)(40cm)
- ar.(triangle)=(11cm)(20 cm)
Orange ar.(Triangle)=220cm^2
Answer: 38°
Using cosine rule,
a² = b² + c² -2bc cos(A)
Insert values from diagram
14² = 18² + 22.8² - 2(18)(22.8) cos(A)
196 = 324 + 519.84 - 820.8 cos(A)
-820.8 cos(A) = 196 - 324 - 519.84
-820.8 cos(A) = -647.84
cos(A) = -647.84/-820.8
A = cos^{-1} (-647.84/-820.8)
A = 37.88°
A ≈ 38°
( x-5 ) (x + 6 )
multiply
X times X + 6x - 5x - 5 times 6
connect like terms
x squared + 6x - 5x - 30
Answer is
x squared + x - 30
Answer:
- 1.625 and 2
Step-by-step explanation:
If you take 4 and multiply 1.625 you get 3.25 (Negative) then you multiply the 1.625 to 2 (positive) and it makes, -13.
Answer:
4
