I’m pretty sure it’s 93. since a complementary angle is equal to 180, 87 + 93 = 180
P=(15x-2+4x+7)2=(19x+5)2=38x+10
Answer:
Figure RST is congruent is R´S´T´
Step-by-step explanation:
Given that R´S´T is a reflection of RST, we know that is a rigid transformation, so it is congruent (the same size & shape).
Answer:
y = - 10
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 2 when x = - 4, that is
2 = - 4k ( divide both sides by - 4 )
= k, that is
k = -
y = - x ← equation of variation
When x = 20, then
y = - × 20 = - 10
Answer:
47.13
Step-by-step explanation:
Circumfrence= 2 x pi x Radius
2 x 3.142 x 7.5 =47.13
