若角α、β满足-90°＜α＜β＜90°,则2α-β的取值范围是_________理由?

已知α、β满足-90° 若角α、β满足-90°＜α＜β＜90°,则2α-β的取值范围是_________理由? 若角α,β满足-π 关于不等式的数学题已知角α、β满足-90° 若角α,β,满足-π/2 若角α,β满足-π/2 若角α,β满足π/-2 若角α、β满足π/-2 若角α、β满足π/-2 若角a,p满足-90° 若角a,p满足-90° 若角α,β满足-π/2＜α＜β＜π/2,则2α－β的取值范围是 设α.β.γ满足0 若α,β 满足-π/2 设α.β.γ满足0 设α,β满足条件-π/2 设α,β满足条件-π/2 已知角a,b满足-90°＜a＜b＜90°,求2a-b的范围.
