Answer:
x = 45
Step-by-step explanation:
We see that the triangle is both a right-angled triangle and an isoceles triange. This means that the three angles are:
a 90
b = c
c = b
We also know that the maximun amount of degrees in a Euclidean triangle is 180 degrees, so
2x = 180 - 90
180 - 90 = 90
90 = 2x
90 / 2 = 45
So, x = 45
Answer:
x = -6
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
2(x - 7) = 5x + 4
Step 2: Distribute parenthesis
2x - 14 = 5x + 4
Step 3: Subtract 2x on both sides
-14 = 3x + 4
Step 4: Subtract 4 on both sides
-18 = 3x
Step 5: Divide both sides by 3
-6 = x
Step 6: Rewrite
x = -6
Answer:
b
Step-by-step explanation:
r=d/2=11.4/2=5.7
slant surface area=2πr*h=11.4×3.14×4.4=157.5024 cm^2
area of base and top=2(πr²)=2×3.14×(5.7)²=204.0372 cm²
total surface area=157.5024+204.0372=361.5396=361.5 sq. cm
