It is 800 b because 40 times 20 ( half of 40 =800
Q1.
Angle BAD is adjacent to angle CAD
which means they are equal
so angle BAD = 26 degrees
Q2.
Angel BAC = the sum of angles BAD and CAD
because they are adjacent angles
To find the angles we solve the equations
9x-5 = 3x+7
9x-3x = 7+5
6x = 12
x = 12/6
x = 6
Answer:
-1
Step-by-step explanation:
i²=√-1*√-1=-1
The answer is A I am pretty sure. This is because in choice B, you would be dividing 7 and the sum of x + 5. In choice C you would not be multiplying 7 and the sum of x + 5. When he question asks for the product, it is asking for you to multiply. In choice D you would not just be squaring y, you would be squaring 2xy, which is not what we want. We only want to square y, therefore I believe the correct answer is A.
Answer:
a) Triangle.
b) Triangle.
c) The area is 110 cm.
Step-by-step explanation:
The shape is given because it is a cross section of a Pyramid which we can see shaded in grey.
The area is given by the base times hight devided by 2. So 10cm * 22cm/2= 110cm.
Hope this helped ;)
