Answer:
Sides are x and x + 3.5 cm
Perimeter = 2(x + (x + 3.5))cm
4x +7 = 67
x = 15cm Answer

Answer:
To find the angle RST we have to first find SRT As the exterior angle adjoined with SRT =53°
so the SRT = Outer angle adjoined with angle SRT
angle SRT = 53° [°.° vertically opposite angles are equal]
Angle SRT + Angle STR + Angle RST = 180°
=>53° + 75° + Angle RST =180°
=> 128° + Angle RST = 180°
=> Angle RST =(180-128)°
= 52°
SO NO. <em><u>C</u></em> IS correct what Cate says is absolutely right
Answer:
You CAN do it. triangle with the circle. find area of triangle first and subtract circle. (8*8)/2 = 32. minus circle. (2.5*pi^2) = 24.674011. so we have 32 - 24.7 (rounded) = 7.3 for triangle. as for the other? divide it into segments. we have a rectangle on bottom followed by 2 triangles on top of that rectangle. Recangle height is 2 * width. The width is 8 as we can see the top. 2*8= 16. plus the triangles. we know the triangle height is 6 minus the 2 from the rectangle height so 6-2=4 times the width which is the rectangle width minus the 6 from the middle divided by 2 because there are 2 triangles. 8-6=2/2 = 1. height * width = 4 divide by 2 = 2. that is the area of one triangle. but because there are 2 triangles multiply by 2. 2*2 = 4. 16+4=20 for the area of the second figure.
Step-by-step explanation:
a² - b² = (a - b)(a + b)
49x² - 9 = (7x)² - 3² = (7x - 3)(7x + 3)
