Answer:
-19
Step-by-step explanation:
2×2-2z4+y2-x2+z4
now we put the value,
4-2(2to the power 4)+(3 to the power 2)-(-4 to the power 2)+(2 to the power 4)
4-2×16+9-16+16
4-32+9
4+9-32
13-32
-19
please check the answer again i am sorry if it's wrong
You find the area of a triangle by using 1/2*b*h where b is the base and h is the height. since we already know the area is 20 and the height is for you plus them in so the problem would be 20= 1/2 (b) (4) then you multiply what you know together to get 20= 2b and then isolate the b by dividing both sides by two so the base should be 10 m
Answer:
x=70°
y=30°
z=20°
Step-by-step explanation:
You first need to find y, which would be 30 because the sum of the first two angles is 150, and a triangle has 180 degrees, so 180-150=30.
By finding y, we can now find a, because if you take the entire triangle, y+z must equal 50. So, z=20 because 30+z=50.
And finally, we can find x to be 70 since the sum of the two other angles is 110 and 180-110=70.
