Answer:
27.2 mm²
Step-by-step explanation:
Area of the triangle = ½*base*height
base = 8 mm
height = 6.8 mm
Area = ½*8*6.8
= 4*6.8
= 27.2 mm²
The tangent of the angle would be given by 14/18, so the angle would be:
tan⁻¹(14/18)
= 37.9 to the nearest tenth of a degree
Answer:
It will be (-4,-4.5)
Step-by-step explanation:
Answer:
(6a + 5b)(6a - 5b)
Step-by-step explanation:
Rewrite the expression in the form of a² - b²:
(6a)² - (5b)²
Use the difference of squares (a² - b² = (a + b)(a - b)):
(6a + 5b)(6a - 5b)
